Seems that projects with GMLive aren’t running in GMS 2 2022.1.464 because of Feather feature. Of course since Feather is in alpha stage and have bugs even on smallest possible projects, this seems to be Feather issue rather than GMLive and for now there’s no sense in fixing anything on GMLive side, I’m rather writing this post to inform, that if you want to test Feather, and project loading hangs - this might be the cause (probably too many code, or it crashes on some specific syntax). Further betas will for sure solve it.
Edit: as for now, leaving GMS beta version for 10-20 minutes seems to finally load project.
