HELP! BG3 failing to launch on Steam (programming.dev)

This is driving me crazy. I'm trying to run BG3 and I'm running into a variety of errors:

My step up:

OS: Ubuntu 22.04.3 LTSKERNEL: 6.2.0-26-generic CPU: AMD Ryzen 9 7950X3D 16-Core GPU: AMD Radeon RX 7900 XTX (gfx1100, LLVM 15.0.7, DRM 3.49, 6.2.0-26-generic) GPU DRIVER: 4.6 Mesa 23.3~git2308230600.fbf3f6~oibaf~j (git-fbf3f64 2023-08-23 jammy-oi RAM: 63 GB

One seems to be this for which I feel I've tried every googable solution:

You must install .NET to run this application.

App: Z:\home\peafield.local\share\Steam\steamapps\common\Baldurs Gate 3\Launche r\LariLauncher.exe Architecture: x64 App host version: 6.0.18 .NET location: Not found

Another is this:

ERROR: ld.so: object '/home/peafield/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

But I'm not even sure what this points to now.

Can anyone help? Or is anyone going through something similar with a similar set up?

EDIT: The solution, as many of you suggested, was to just change distros. I'd heard good things about Fedora so I tried it and everything ran first time with no tweaking! Thank you everyone for the advice.

I don't exactly remember, but I know that I had the launcher running for the first times, and in it, I disabled it so the game launches right away.

One thing I had in a different game, was a edge process (certainly to fetch news or something) that failed and that was the process I had to kill so I could see the launcher.
I use btop in the terminal to show processes and I filter with the approximate name of the process I want.
If you don't know the executable name, you can filter steam and it'll show steam and the sub-processes that are running.
From there, you can simply select edgeUpdate ( I think that was that) or DirectXInstall (both used to cause me problem when launching games for the first time) and use the kill button and see if the game launches.

Okay I'll try that too! Thanks!

Finally, did you manage to run the game?

I did, but only by installing another distro (Fedora).
