Hi @lacosmok,
Sorry to hear this.
I know you’ve mentioned reinstalling Vermintide already, but could you please try performing a clean reinstallation by also removing your AppData directory. You can find how to do this, here:
Ah okay! Have you made any recent changes or updates to your PC?
It may also be worth trying a Selective Startup, which can help diagnose whether a background application is resulting in your issue. This can be performed by:
If the issue no longer occurs after having performed the Selective Startup, try re-introducing your programs one-by-one to determine which is the culprit.
Hmm, another shot in the dark, but can you load in correctly in Modded realm? (chosen from the launcher options)
As EAC only applies to Official realm, this can help in identifying if the issue is EAC-related in some way.
If so, I recommend to next try adding Firewall and Anti-Virus exceptions for both Vermintide 2 and Easy Anti-Cheat:
You’ll want to ensure you have the following exceptions in place:
devtrackers.gg
\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\binaries
\Program Files (x86)\EasyAntiCheat
Another thought, are you using a VPN or any mods?
If so, can you please try disabling these and check if there’s any change?
Gotcha. There are unusual references in your log to Easy Anti-Cheat, Razer Chroma and Twitch - so I’m suspecting the issue may be EAC-related.
As above, can you please check Modded realm and see if that works?
After that, I recommend to try disabling any Razer software to see if there’s any change.
Hm I’m scratching my head a bit with this one! 
If possible, can you temporarily hook your PC up to a mobile data connection and see if the issue persists?
If you can load in and select a character with the mobile connection, then this can point towards a network/connectivity issue.
