Anki 2.1.43 crashes on sync (access violation)

Anki Desktop
1

Hello.

Anki crashes on startup. After some investigation I managed to start it after I’ve deleted local profiles (removed folder). Now anki starts with empty dicts, but crashed on first try to sync.

I have other copies on another PC, android phone and web and there is no problems there. Modifying of graphics settings didn’t change anything.

The issues appeared after several installation of different anki version. (2.1.41–2.1.43). (I was trying to get rid of some glitch with Anki showing no statistic for “current” deck)

Win10 64 1909.

Maybe some other tool on your computer like antivirus or firewall software is causing the problem - you’ll need to experiment I’m afraid.

3

Well, I have similar set of software both on laptop (where crash happens) and PC.
I’m not the only user who encounter this issue (Crash desktop Anki on syncing (Win 10 64bit)).
In any cases even if there is some problems with antivirus or firewall or somethink it’s would be better to show dialog box, describing problem. Now I have no ability to investigate the problem, because I dont even understand what resource had access vioulation.
Could this issue somehow be transfomed into bugreport on github?

I can not fix a problem that I can not reproduce on a machine here. You have two machines, one of which works, and chances are there’s some difference in configuration that is causing it. I suggest you experiment with installing/removing any differences in software to see if that helps, or as a last resort, try a Windows reset.

5

Thank you for you reply.

I’ll try to figure out differences in installed programs.

Is there a way to run some debug version or somehow else pin down place where exception raises?

Hello,

I have found the culprit, that was “Avest SCP” out local cryptographic utility to file taxes. It was installed on both computers, but created troubles only on one.

If someone need to find root of problems in the same conditions, еasiest way to run debugger (Microsoft Visual Studio in my case) and attach ше to running anki application. Then exception is thrown the debugger can show exact dll that caused problem.
