Invisible after Playing

Hey there,
sometimes i have the Problem, that after playing like 10-20 Minutes my Weapon starts to get Invisible or even my Playermodel or Playermodels at the end Screen. Until now i dont have any other issues, the game runs good, everything feels good, but hopefully this gets patched soon (thats the reason for creatings this post)

Thanks for reading, sorry if someone already reported this
Have a great day <3
