Cannot upload sketches to arduino uno.

Hey everyone. This is my first time using arduino and first time posting onto the forums, but I've hit a bit of a snag and have no idea what is going wrong. I have been messing around with some basic sketches and whatnot with my new arduino uno, but recently I have not been able to upload to the board. It stopped suddenly and I don't know what I changed or did. Every forum I find that seems to have the same issue as me seems to have the solution as wrong port or board type in the IDE, but I am pretty sure mine are correct. I have tested on multiple computers and had the same issue.

Here is the error code i'm getting.

Arduino: 1.8.12 (Windows 10), Board: "Arduino Uno"

Sketch uses 924 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.

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

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

Let me know what I can do or if any more info is needed. Again, I don't really know what I should be looking for. Thank yall.
