An Unknown error has Occurred while exporting in Photoshop

Hey all,

I have been using Photoshop more regularly as of recent and I have started getting an unknown error when I try to export as and Quick Export to PNG is just not doing anything. When I try to 'export as' the loading/preview screen is blank and just spins while the share button in the top right blinks slowly. I have my prefferences set to restart after I close photoshop but, haven't yet. I am on the 2021 version of the software and figure before testing it would be good to show the error message just in case and I will update if the restart with preferences resetting will help. To note, yesterday I was having trouble fully closing photoshop and couldn't kill the app in the hotbar area in the bottom right on windows. It wouldn't allow me to even open a right click selection menu on it, so I had to forcibly kill it in task manager. Anyway here is the offending error:
