I asked Chat GPT for help and followed all of its advice but nothing worked. Tried to uninstall, reinstall in different folders, tried starting a new project, tried changing the folder. Tried running as administrator, changing computer permissions. I don’t know what else I can do. When I try to run the “uploaded” experiment I just get a white screen with four 404 errors of the files that are supposed to be in the lib folder (that doesn’t appear in pavlovia).

Please help, I told my researcher employer I will be done by Saturday but I can’t even start working on it!!

someone please help

It definitely looks like a permissions issue with that folder - try copying the relevant project files to a new location which you definitely have access to and creating a new project from them.
