Does this happen with factory settings on the latest build?

Philipp Oeser (lichtwerk) triaged this task as Needs Information from User priority.

Also cannot reproduce, will put this on hold until todays (or newer) build has been tried...

Tried 69b2f5268114 version and I still have the same issue.
The issue happens every time I try to select any vertex/side/face in edit mode(Or click anywhere while in Edit mode and using a pointer(not cursor)) and use some specific tools like Knife, loop cut, but not extrude(all faces since can't choose specific) and not transform tools.

Does it crash every time in a reproducible way, or is it random?

tried 036ec5cae4f7 and the issue's still there.
Yes, it crashes every time (100%) I try to use the tools in any way(hotkeys, toolbar, sidebar and every time I try to select anything with box/pointer selection.
BUT, as it turns out this problem occurs only when I edit meshes, metaballs, and bones. Blender doesn't crash when I edit(select points with pointer/box-selection) curves, surfaces or grease pencil (strokes?)

Blender doesn't crash however if I try to select mesh's components via select menu like select random and select similar by<...>

If there's any way of logging Blender's activity and figuring out why is that happening, please let me know, thanks!

Just tried these builds on another computer and couldn't replicate the issue on MY PC. It's been a week already, please let me know if there's any way of debugging this.

Thanks for a reply, I tried using the debug mode, here's a log

I can't redo this error but most likely D4350 will fix this.

Note that D4350 will most likely resolve this issue, although it's not yet finished so a short term fix would be good too.
