Notes:
- The issue was not reproduced by CQA
- The issue seems to happen randomly for the user with no clear reproduction steps, apart from the ones mentioned at the top of the description (steps above might be incomplete and some might be unnecessary)
- The issue started happening after a license check, however, they report that it seems to be more of a general issue rather than a license check-related one
- Full error message from the user’s Editor.log is in the internal comments
