Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

yes, i had to build from source (more on that later (in P.S.)), 5.0-18160

Is the issue present in the latest stable version?
yes 5.0-17995

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[First broken version number here (if applicable)]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

ASUS Prime x570-Pro
Ryzen 5 3600
EVGA RTX 2060 KO
32GB Ram
Linux

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

crashes near instantly before a log can be produced (trying to use the "show log option that's built in)

P.S. a little off topic, but with the steam deck stating to gain traction. i think its time to have an official way to install dolphin without building from source, the ppa (which i assume this is supposed to be: https://launchpad.net/~dolphin-emu/+archive/ubuntu/ppa) looks like it doesn't exist. and the flatpak is unofficial, and doesn't keep up with dolphin updates as frequently (based on looking at the commits for it and this: https://github.com/flathub/org.DolphinEmu.dolphin-emu/issues/99) they only update it every progress report. which leaves compiling from source to be the only official way of getting dolphin on linux devices (and steam deck users who have never used linux before, are unlikely to do this). and from what I've read steam deck users are going strait to the unofficial flatpak

TLDR: Have a look into different way to package dolphin for linux, because new users will avoid compiling from source
