Roon is fascinating and frustrating. When it runs we have joy, when it gives problems frustration comes. For me, the logs point to exception errors in ntdll.dll. The entry point to server registration, so I go searching:
Google search with “roon ntdll.dll crash” as the best answer I see:

There have been cases where Roon has had issues with multiple GFX card setups and with GFX drivers… I might try removing the 2080 card and see if you can work without that for now.
Clear but deleted words in the forum itself. That current Roon builds probably do not yet show 100% compatibility with nVidia drivers, we are not told so directly.
I have this common graphics card and problems with Windws10 directly or in this system: ntdll.dll, version: 10.0.19041.1023 System information: Wine build: wine-6.15 Platform: x86_64 Version: Windows 7 Host system: Linux Host version: 5.13.11-1-MANJARO
The standard answers so far (see below) are:
reinstall the whole system or Roon, do all updates also for the graphic cards, disable virus scanner and firewall, take 32-bit version, observe problems, send logs…
The community still gives these hints:
