I know that running Vortex is a pain but I never ran into any problems once it was installed. I did this back in 2022.
I don't want to discourage you, but what's wrong with helping MO2 and Vortex get ported to Linux?
MO2 works fine on Linux! It’s a bit slow to start but I found it very usable, a bit less polished than Vortex maybe but it absolutely gets the job done and I got my head around it inside of an hour.
Vortex at one time did have a native Linux version. IIRC, it had very minimal game support, lagged behind the main branch, and was eventually canceled. I don't think they're interested in contributions for native Linux. A separate app seeking to implement Vortex API and package support would potentially be more free to improve the UX, do Flatpak/Appimage, or use more interesting Linux features like overlayfs and FUSE archive mounting. I have a mind to try my hand at it, would be a good starter project for a new language.
