Lately I have been getting this Issue when opening my project and I’m not sure what to do about it.
I have looked up similar problems on the forum but all of those posts seem to be a few years old and dont have a clear conclusion.

There are a few things to note here as well. First of all, it doesnt happen all of the time. Id say that 4 out of 5 times when I open the project it pops up, but occasionally it wont.
Also, after I click OK there doesnt seem to be anything wrong, as far as I can tell. Theres no black screen preview and everything loads like it should, but im afraid to change anything edit anything incase it corrupts or something.

This started happening randomly like two days ago and I still havent found a solution so I would really appreciate any help I could get here, thanks.

There could be some clues in this thread from a month ago. Functions error since update

Yes it looks like the same problem I had in the thread link above…I went back to the previous version of gdevelop. It’s only a problem with that one project and so I’ll update gd once I’ve finished that project.

Hello @Sir-Hanz would you be able to share this project by sending it to hello@gdevelop.io ?

We can’t reproduce this issue on our end, so we need a project to be able to fix it.

Thanks

Update: I still dont know the cause or official fix if this were to happen to someone else. But I was able to fix it on my end by reinstalling the gdevelop app. I think it may have something to do with clearing my cache or maybe I had a corrupted install file from an update.
