It looks like whatever file you had open last is linked to a Pavlovia project which either no longer exists or has changed, so when you open PsychoPy it opens that file and attempts to sync but errors. The best solution here is probably just to reset your user settings, which you can do by (in Windows File Explorer) going to:

%AppData%\Roaming\psychopy3

and then deleting the file appData.cfg, when you next open PsychoPy it will make a new appData file with no file history so won’t attempt to open the file which was causing the error.
