The latest version of the normal branch of GameMaker (v2023.8.1.148) causes PFE to crash on the stage select. This is due to backend changes in GameMaker.

PFE officially uses the LTS branch of GameMaker. If you are just starting your game in PFE, you should redownload PFE and switch to the LTS branch of GameMaker. You can find a tutorial for downloading the LTS branch here.

If you have made a lot of changes already, revert your GameMaker to a previous version to avoid this crash. You can do this from Preferences -> Runtime Feeds -> Master.
