That's still the OBS SESSION log, not the crash log.
The crash log is in %appdata%\obs-studio\crashes.

This couldn't be coincidence (to cursor copy crashes). memcpy is unsafe operation, is anybody even working on this issues (gs_texture_set_image from libobs/graphics/graphics.c)?

The bounds of memory copy, I think. Changes to code required.

Anyway, Alt-Tabbing is not recommended. Use hotkeys or whatever else.
