try Window + R cmd will open enter the %temp% and call cache will open select all then delete it.

delete the test folder from your project it will work. If you will delete the test folder it will not affect you remaining project. If it's not working inform me

Answer 3

It seems like your studio crashed. You need to clean your android studios cache folder. It is located at

On Windows: C:\Users\%USERPROFILE%\.AndroidStudio4.0\system\caches

.AndroidStudio4.0 - choose your latest android's version here

close your studio first. Then delete this cache folder. After then restart your studio project. It will looks perfect after restarting.
