Can't save project B after saving project A

Hello
I created, renamed and saved my first project (project A) without issue.
Then I started to work on project B. When I tried to save it, the saving screen displays “…”, I can’t click on save or save as. I am not sure how to proceed, I don’t want to lose my work. I read the manual and searched online but no success.
thanks for your help!

Careful with that link…
