Cant go to the CMS. Bootstrapper.aspx not found
Your logged in session might be struggling to load assets in the modules folder.
Try
- User you are logging in has an Administrator role? (This is assuming default roles haven't been modified)
- Try creating a new admin user using whatever user manager has been setup against it. It'll either be membership or identity.
- Check folders permissions if you're hosting in IIS
- Reinstall nuget packages via package manager

I am picking up on a old project on CMS 11 for some fixes and when trying to load the CMS edit section, I get error as Bootstrapper.aspx not found. "System.ArgumentNullException: 'Value cannot be null.
Parameter name: UserName'".
