This morning when I checked my computer I found that Tixati v3.35 had crashed when I tried to open it from the system Tray (Windows 10). So I restarted it as this has happened before. It started as normal. But as soon as I right clicked a download intending to do a forced check, it crashed again. I restarted it again just selected the download's option tab and clicked force check there. It started checking but after a bit it crashed again. So I checked for upgrades and decided to upgrade to v3.36. The upgrade was successfull. I restarted Tixati v3.36 and it started. But after a couple of seconds after having loaded fully it crashed again. I renamed the appdata\Roaming\Tixati  and restarted Tixati then imported my latest backup export which I've set on a schedule. It imported the list and all settings (all checkmarks) and restarted. And crashed again after a couple of second. Every crash is with a windows dialog popup "Tixati has stopped working: A Problem caused the program to stop working correctly. Please close the program." with a "Close the program" button.
I don't know why the program suddenly decided to stop working. I haven't changed anything or even added any torrents to it in the past 2 days.
There are however a lot of torrents (2000+) in the torrent list. The program takes around 4GB of memory but there is 32GB physical memory installed on this system of which only 54% is in use prior to launching the program.
How can I resolve the issue? Is there a log file or something that I can check to see why the program crashes?

It might have been a windows issue. (Network stack or memory heap corruption or something) I've restarted the computer, did a chkdsk /f on my drives to rule out filesystem issues (didn't find anything) connected my VPN and started Tixati again and it's been working as normal for the past couple of minutes.
I'll leave the post for anyone who's gotten similar issues.

Stress-test the memory, too, and re-insert the modules a couple of times. There's built-in memory tester in Windows, or bootable memtest86. You can even use regular 7-zip test with giant windows sizes to cover most of free memory, but there's always a chance that the damaged memory cell falls into some other area.

did any other programs crash or act funny?

were you able to send in the crash reports?
I doubt this is your problem, my tixati has over 7000 torrents, and in many channels. I use about 6GB of my 32GB, and never crashing on Linux.
