After publishing my project, if I were to change package ident - new *.csproj generates. I would not give a fcu bout it, but it blocks me from opening scripts via inspector editor. Even after reopening the project

Solved
1. Delete all .csproj files in Code folder
2. Delete all .sln files in the Project folder (root folder where you have .sbproject file)
3. Reopen project
