crash on starup - Invalid pointer operation

Hi

We have been using HeidiSQL for years to connect from a Windows server to a Linux system with mariaDB. We have never had problems with different systems and operating systems. For a few days, HeidiSSQL has crashed with the following report every time it is called:

I thought if I uninstall and reinstall HeidiSQL it works again. Unfortunately not. Then I searched the registry for HeidiSQL entries and deleted them. Then reinstalled. Still the problem. The portable version brings exactly the same problems.

Of course I rebooted the server. No change either. Then I uninstalled the newer VC Redist and installed the one that came with it. Again nothing. Unfortunately, I couldn't find any posts on this subject in this forum. Unfortunately, a Google search was also unsuccessful. What can be the problem here?

I recommend to update to the latest build through the session manager's "More" button > Check for updates. Or wait for the next v12.4 release.

Thanks for the quick help. HeidiSQL is running again. I had to download the update with another system. I then copied heidisql.exe and its running.
