Can't terminate cubase after update 10.5.20

When closing a project, cubase crashes.
Had no prior problems.
Is it possible that the update was not installed correctly?
can I re-do it?

Please check if this happening with the same project or with all the projects…
(To me it happens with some specific OLD projects, all the time…
Cubase crashes on exit and I need to terminate it)…

If not try to open in safe mode…
