Launcher project by the designer

maxime.guenet · May 25, 2023, 7:01am

Hello,

For two days, I have been unable to launch my projects via the designer.

I attach below the error message that came to me, has anyone already encountered this problem?

Thank you in advance

Wish you a good day

EDIT : I just managed to start one of my projects, for this I restarted my PC and deleted the cache folder, and it seems to do it.

I wonder if I don't have compatibility problems between a version of python and certain file that is generated in the cache.

That stack trace makes me believe you have a script that executes at start up, and that script fails.
More accurately, it fails because you're trying to access an item that doesn't exist, in an empty array.

PS: I happen to work on some of that company projects, if you want to contact me privately and in french with more details, you're welcome to do so.
