PolyMC VS MultiMC5

No, not really. No one was in charge at the beginning. It was a community project with multiple people having the administrative role at the same time. LennyMcLennington was one of the contributers, but not really an important one. But he removed the administrative rights from the actually important people. Devs like flowln and Scrumplex played a much bigger role. Even after half a year being the only developer at the PolyMC-Project Lenny still heasn't caught up with what other conributers had done in a few months before.

Could I suggest trying a different launcher such as PolyMC? You can get this on deck in Linux linkand sign into your microsoft account to access Java. This version also has the benefit of you being able to get modpacks.

It's still open source, the repo hasn't moved. https://github.com/PolyMC/PolyMC/

The issue is: the main developer freaked out, made a post ranting about political bs, kicked everyone from the GitHub project and now it's been 2 months since it hasn't been updated. The developers who used to contribute to "PolyMC" moved from the "PolyMC" project to the "PrismLauncher" one after the drama.

There was no prompting or provocation towards lenny at all. The code of conduct existed for ages before lenny deleted it on oct 17 2022: https://github.com/PolyMC/PolyMC/commits/358f080c76dbdfc65f32e08448a5e38b78d2bab0/CODE_OF_CONDUCT.md

First, it's gio that handles trash in SteamOS. Second, after digging into PolyMC's code, it also leverages trash. Was added roughly 7 months ago in this commit: https://github.com/PolyMC/PolyMC/commit/02f30de1c11fa53e61c199032a3280afe618e3b2

probably not with an unmodded version. if you want to use a different launcher for whatever reason i would recommend taking a look at MultiMC (https://multimc.org/) its a free multi platform launcher that lets you log in with both mojang and microsoft accounts and lets you have multiple installations of minecraft in the same launcher (very nice with modpacks so that you don’t have to keep messing around in the mods folder) its works on macos, linux and windows. so if you are using the old launcher because the new one doesn’t work on your current operating system this launcher might just work!

See some screenshots here: https://multimc.org/

I use Multi MC for addons and mods. https://multimc.org/ might make it easier.

Honestly Just get GDlauncher or MultiMC , both eliminate the need for the overwolf FTB hybrid. GDlauncher is pretty straight forward , I dont personally use MultiMC but alot of people do so theres bound to be guides on yt .

MultiMC is what you're looking for. It tries to retain compatibility with very old MC.
