My arduino isn't recieving uploads anymore for some reason

I used to be able to upload things and now I can't. The error code isn't helpful for me. I hope somebody on here can use it to help me. Arduino: 1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board: "Arduino Uno"

Sketch uses 946 bytes (2%) of program storage space. Maximum is 32256 bytes.

Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

I suggest to uninstall the Windows Store version and install the normal app (Windows Installer for Windows 7 and up); Windows store version is known to cause some problems at occasion and this might be one of them.

It didn’t work

Try ballscrewbob's cleanup instructions.

Uninstall, cleanup, install.
