Greetings @leighjboyd,
Sounds like a similar error as this user experienced: VS2019 Torizon Debug
If you see the answer it seems that the file had incorrect ownership. The customer here was able to resolve this by changing ownership to their current user.
I imagine when your IT team gave you a new user ID, and other changes it must’ve messed up the ownership on the files in your project.
Best Regards,
Jeremias
