Update:
Managed to play without Mods without getting any Error, weird stuff.
As well managed to play with selected Mods (My Community one's) for morethen 2 hours without any crash.
I'm close to pin it down to the MCC-Mod.

For me, problem looks solved so far, i'll create/reactivate an Issue if problem rises again.

Thanks for your help!

Hello Koala,
just uploaded both, the Arma-Report-Log and 2 Versions (2 Days) of the crashdumps. 'I am sorry, at creating of the ticket i messed up the upload-files.
I managed to play over an hour without any mods crash-free so far, as well as same time with mods.
I'll keep testing if i can point the problem out to a single mod, if the vanilla-version is running fine so far.
