Game freezing on startup loading screen

When launching the game, as the initial loading screen begins, and the loading "wheel" (box/square?) to indicate loading begins, the game will freeze almost immediately. There is no crash to desktop or error messages, the game simply freezes and I have to close the game through the Steam launcher, or closing the program through Windows. 

Sometimes (not often at all), the game will load correctly, and I am able to search for a match. Loading into the match poses no issues, I choose my class and loadout, and play through my first life flawlessly. However, upon dying and loading the spawn screen, the game will then freeze completely after a maybe 1/2 second delay of spawn screen appearing.

I am able to temporarily fix the issue SOMETIMES by:
1. Restarting my computer (Fixes the issue most of the time, sometimes it only lets me get to the spawn screen as above, then a restart again will fix it)
2. Setting shader cache to 0GB in Nvidia app, restarting computer, setting shader cache to default in Nvidia app, restarting computer again (This might just be because the computer is restarting)
3. Uninstalling and reinstalling Javelin anti-cheat with no PC restart has worked previously, but not recently.

This freezing issue has been happening for at least the last month. I have verified game files through Steam (which always detects a missing file and redownloads, but doesn't fix the issue), deleted config .ini files in "Documents" and "appdata", uninstalled the game and reinstalled, uninstalled EA app and reinstalled, and disabled game overlays such as RTSS, Discord, and Steam. but this does not help.

The issue started during Season 3, unsure if before or after midseason update. Still happening with Season 4 update. Please let me know if there are any logs or further info I can attach to help identify the issue. I've attached a short video of when the freeze occurs during startup.
