PROS program upload denied access

Hi! I have recently switched to pros, and very recently I have encountered a problem where I try to upload the program and I get an error message that says “could not open port ‘COM6’: PermissionError(13, ‘Access is denied.’, None, 5)” Does anyone know howto fix this? I’ve tried the “have you turned it off and back on again?” solutions, and searched around in the settings a little bit, but cant get anything I do to work. I am running Windows 10

The most common cause of this issue on Windows is if you have another program like VCS or the V5 Firmware Utility open at the same time. Both programs like to connect to the V5 and stay connected - PROS will only connect to the Brain when you need to communicate with the Brain (like uploading code). Can you verify that they are all closed?
