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?
