Describe the bug
Use a profile with space(s) in it. IE Valheim Mod Pack

To Reproduce
Steps to reproduce the behavior:
Create modded instance using BepinEx and BepinEx mods. Name the profile something with spaces.

Ensure the parameters are set in Steam Valheim with the %command% at the end as instructed.

Run modded, and observe it start, then stop. No error messages or other indicators as to why it's failing.

Expected behavior
Do the above but leave out the spaces for example ValheimModPack

Observe R2modmanplus execute Valheim with all mods loaded.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
Spaces can be a problem on Linux. Profile names for app image or linux installs should enforce this particularly if passing arguments to Valheim.
