Please describe more exactly:

• did you import that file by loading it into an editor, or did you use File > Run SQL file?
• are you using a theme other than the default "Windows" theme? (e.g. a dark theme)

[CraftedRO]

I drag and droped the file then press execute button.
Yes I use Windows 10 SlateGray theme.

[ansgarbecker]

Then please retry with the default Windows theme in Preferences > General > Style/Theme. Don't mix it up with "Windows 10" by the way.
If the crash does not appear with that Windows theme, the crash is theme related.

[CraftedRO]

Today it crashed with default theme , with clean portable version and default settings:

I have to mention that database was also opened in other application too.

I see the callstack but I cannot reproduce that crash here. I also see there was a automatic reconnect on your side when you made the screenshot.
Can you post the imported sql file here? Only if it does not contain sensitive information.

its actually public as gist atm here : https://gist.github.com/CraftedRO/c3dd3b3d43d59e732635ca6fe0666a7a

[ansgarbecker]

Thanks, I see there is nothing special in it, just UPDATEs.
I still could not reproduce the issue, so I am blindly trying things now.
I just made the check before the crash happens more robust. Please update to build 6566 and retry.

Today it crashed even without other apps be connected to database , only heidi.

Is there a chance to be related with innodb_buffer_pool_size = 1024M ?
