The DDM has crashed again a few minutes ago. It ONLY happens when playing Overwatch. It's very annoying, because my ingame character is out of my control for a few seconds after DDM.exe crashes.

Some recent entries from the file ‘Win_DDM_v2.3.2.18.txt’. The DDM.exe program crashed at around 21:29:

@plkov​ 

Have you tried the previous version, 2.3.1.16? I've installed that version here and have had no crashes up to now.

Referring version 2.3.2.18, here the issue causes keyboard problems just before DDM crashes. 

Had crash again yesterday. Same errors showed by event viewer.

I tried version 2.3.1.16, but DDM crashed after an hour of playing Marvel Rivals. So i reinstalled the latest version, 2.3.1.18, and now it only crashes when playing Overwatch xd
