There's an issue with clicking on 'projects' in the breadcrumb trail, the part of the file browser that shows the path separated by '>' and lets you click up the folder structure. If you click on 'projects', the API is returning the new error about not being allowed to access that folder, but the frontend doesn't handle that error in any way, and the file browser gets stuck at 'Loading files'.

Ideally, the breadcrumb trail would not show you a folder level that you're not allowed to select - the first item would be . That way, users aren't even aware that there's a folder they can't access. If for some reason that proves overly difficult to implement, then the file browser should catch the new error that the API is returning, remove the loading message, and probably make a notification that that folder is inaccessible.
