Open instance folder button not working on Linux

[Ryhon0]

Describe the bug

Clicking on the "Folder" button on the instance screen does not open the instance directory and prints this to the standard output:

egrep: warning: egrep is obsolescent; using grep -E
xdg-mime: no method available for querying MIME type of '/home/ryhon/.config/com.modrinth.theseus/profiles/1.20.1'

Steps to reproduce

1. Click on an instance
2. Press the folder button

Expected behavior

Instance directory opens in file manager

Additional context

Running the AppImage release on Arch Linux
App version: 0.5.0

Bug is present on Nobara 38 as well

Doesn't work on Ubuntu either
Edit: Well some of them work but open in chrome instead of my file manager

This is also the case on Linux Mint (21.2 Cinnamon)
each time the instance "Folder" button is pressed the error

nemo: symbol lookup error: /lib/x86_64-linux-gnu/libxapp.so.1: undefined symbol: g_memdup2

is printed to the console.

I may also add that even the game itself is unable to open folders (open resourcepack folder etc) when launched with modrinth's launcher, so it's quite hard to go the instance folder

This also happens on Kubuntu 22.04.3 LTS, this error is printed:

kde-open5: symbol lookup error: /lib/x86_64-linux-gnu/libKF5GuiAddons.so.5: undefined symbol: wl_proxy_marshal_flags

App version 0.6.2
