Searched the forum and found that the fix to this would be to delete the .local folder and project.json and after open the Main.xaml and these files should be recreated.

Problem is that recently my IT switched from a roaming profile to a local one and I believe this interferes with the creation of these file.

Tried with IT to trace this ourselves and see if there are any blockers (e.g. antivirus) but had no success.
Can anyone please explain how and from where are these files created?

Thank you,
Alex

Hi @Alexandru_Vaduva

Could I have one suggestion first? Could you try to open the project from your desktop rather than a network drive and see if it will help?

Hi @loginerror,

Thanks for the reply, was a good idea, doesn’t work… :frowning:

I will assume this is the Enterprise version of the Studio. In this regard, I would suggest contacting Support first, as they might already know the fix.

I will continue to look for the solution as well.

I did contact support too, so far they haven’t been able to provide the info I requested…
