There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

In 27 European countries for some time it has been considered for introducing a law that would force phones, tablets, laptops, and other mobile devices to use a single USB Type-C connector.
The European Parlament announced that a provisional agreement has been reached and that it was voted that a single charging solution is USB Type-C. The current agreement applies and covers the next devices: phones, tablets, Readers, earbuds, digital cameras, headphones, headsets, handheld consoles, and portable speakers. All currently existing devices can still be sold without issues but starting in the fall of 2024 all-new products must support USB Type-C charging.
The agreement will also hit Laptops but not on the same date, How is USB Type-C currently not enough for charging laptops, all new laptops that will have to use it are scheduled for fall of 2025.
Although the agreement is reached the EU Parliament and Council still have to formally approve everything.
Apple has been targeted as the main target for rules since their iPhones are still using Apple's proprietary Lightning charging port. Apple sells a lot of iPhones in Europe and even though iPad Pro and iPad Air along with all MacBooks have moved to USB Type-C, iPhones are still struggling with the Lightning port.
Apple criticized the EU’s charger rules when they were first proposed in 2021, telling the BBC, “We remain concerned that strict regulation mandating just one type of connector stifles innovation rather than encouraging it, which in turn will harm consumers in Europe and around the world.” The European Union has said in response that it will update its rules as new technology arrives.
The main problem in Europe that led to this proposition was electronic waste which reached 11 000 metric tons in 2018. European union is afraid that this will keep rising as chargers become larger and heavier in order to accommodate faster-charging speeds. More electronic waste means more hardware slowly decomposing in landfills that will contribute to climate change affecting everyone on the planet, not just the people living in Europe.
Error code 0xc004fc03 occurs when Windows users fail to activate their Windows operating system due to a networking problem. The error code’s common symptoms include the following:
Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers. Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.
To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.
To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.
If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.
If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.
Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.
In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.
Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.
Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.
This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.
