Can you provide us crash log?

BTW Valentina Studio on start AFTER crash, can show dialog asking if to send crash log.

On my development laptop (MacBook Pro)

Also using VServer 6.b13

Connecting to VServer DB thru Studio Pro. Open server DB and click on SQL Editor icon and app crashes.

And yes, I have sent in a crash report a few times.

SQL Editor is still under active development, it was fixed in one of the recent commits, so doesn't crash anymore.
Thanks for the report.
