Screen Freeze

Hi,

sporadicly my screen freezes, then it takes a while and the game recovers. This happens to me like every two maps.
Someone made a youtube short video from it:

it does not happen if i restart the game after every map.
while the game is recovering i can tab out and use my browser/discord etc. as usual. So i dont see any things i could do from my side to fix it.

any ideas?
best
