Android Studio suddenly corrupted cannot read xml and java file

Question

I open my previous project and I checked it corrupted as you can see at the picture that I attached. It seems that Android Studio cannot read the file. It is happened after I update my window 8 to window 10 and import open CV library. I already tried restart my computer, after that I uninstall and reinstall Android Studio and I already tried invalidate cache memory.

Answer 1

If you have any backup of your project then add those backup files bcz I remember that when I got that error last month I tried everything but didn't get file back.

Answer 2

Try deleting this folder C:\Users\user\.AndroidStudio3.*\system\caches manually.
