Hello, sorry to hear about what happened to you
Since you cannot access anything on your device and it behaves abnormally, these are possible signs of a virus that can get into your device, try doing a full scan or a custom scan on Microsoft Defender, it can eliminate the virus on Windows if the problem is not solved
I recommend you to use a program from Microsoft here is the official page of the program https://www.microsoft.com/en-us/software-download/windows10
God willing, Windows problems will be solved and your device will return to normal
I also advise you to update your device regularly and check your device on Microsoft Defender regularly for the virus
