Help on this error: PermissionError(13, 'Access is denied.', None, 5)

Basically when I try to upload my code into my board(Wemos D1 R1), this error pops up, it was just fine the day before but today its acting up, I don’t know what I’m doing wrong… Also sorry if this is the wrong sub-forum to post this

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

I don’t suppose you have that serial port open in serial monitor or some other serial application? Close that if so.

It kinda varies on what the problem is, just now when I try to upload it gave me a serial.serialutil.SerialException: GetOverlappedResult failed" with the same error code, PermissionError 13
