Hello all.

Need help with below issue.

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'".

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

Reinstallling the nuget packages worked for me. Thank you.
