Backup game caused crash

I backed up my game in case I made any mistakes. What I did was copy and paste the entire local game folder and named it backup when I opened the backup version it opened fine I then closed the backup and opened the main game which caused Gdevelop to crash and display nothing but a black screen every time I opened Gdevelop.

The only way to rectify it was to restart my laptop I’m not sure if it’s a bug or just a Gdevelop quirk.

I am on Gdevelop 5.4.203
