I have long paths enabled in my registry and still get this issue. It seems like this is a problem with Power BI and / or its dependencies.

The command for this is subst DriveLetter: "path\to\project\folder"; eg, subst P: "C:\Users\username\Power BI Projects". In our case, this trimmed off about 60 characters from the file paths, and we were able to open them again by navigating to them through the virtual P drive.
