Application has encountered unexpected error

I can´t post to Support forums even though I own both RoC and TFT, because I haven´t pre-purchased Reforged.
I tried to launch Warcraft and this message appeared. Has anyone encountered this recently? Is there some known issue with the game and possible fix for this?

This is code I was given for communication with Blizzard in case someone from them sees this:
