Editing AI Tool fails

When attempting to edit the properties of an AI tool I always get the following toast popup:
Script file 'SubFolder1\SubFolder2\Get-MgUser.ps1' does not exist.
I have to delete the tool and re-add it (with the exact same script path).

I'm running 2026.2.0 on windows, as a service.

I have a custom script path configured in my settings (my hunch is it's to do with this, but havent been able to test without).
