Thus, since the actual cause of the 0xC0000005 error is not clear, you should try all fixes provided below.
Note, before you try to fix 0xC0000005 manually, we suggest you try to solve the issue automatically with the help of a repair tool ReimageMac Washing Machine X9 – it is designed to find a root cause of the problem and fix it within a scan. This is especially beneficial for less IT-savvy users.
Fix 1. Check the system for malware
In general, it’s advisable to check the system with a professional malware removal tool regularly. A full system scan is also a must when your PC encounters a system error, such as 0xC0000005, because viruses are by far the most common error pop-up and BSOD causes. Thus, activate the anti-virus that is running on your PC and let it check the system thoroughly.
There are many free third-party applications that offer you trial versions, so a scan with these tools should suffice, although you should make sure that the provider is reputable – there are plenty of fake anti-malware tools that act like malware themselves instead of guarding users. However, the built-in Windows Defender (known as Microsoft Defender as of recently) is more than sufficient to ensure that no malware is involved. The tool has been tested by various independent parties and proved to be just as good as third-party providers, as is ranked as a top product on multiple occasions.
