No Models In Match & More

To preface, I'm playing the Beta through Steam on an RX 6600 XT and i5-11600KF w/ 24 GB RAM on Low and Performance settings.

After running a few matches, I'll be unable to leave the lobby, which results in one of two issues:

1. IF I get into the next match (albeit unwillingly), all player and weapon models cease to exist on screen. This includes enemies and some UI elements every now and then.
   
   
   1. a) The issue preventing me from leaving before a new match is the "Return to Menu" button simply not working.
      
      
2. IF I can leave, or in some cases am still forced into the next match, I'm sometimes left with a black screen. In this event, I'm forced to exit the game either through Task Manager or Alt+F4 as there is no menu for me to access anymore.

When I do exit the game in this manner, I check the integrity of the files, to which Steam says:

What files are these? I'm not sure. But I do know this has happened twice and has been quite disruptive.
