[Bug] [Linux] Some sort of exception gets thrown when I hit save and play

[DizzyDaisy909]

Describe the issue/bug

I got thrown this exception when I hit save and play after adding some mods.

HMM Info:

    Version: 7.13-1
    Args: 
    StartDir: Z:\var\mnt\4c9fd4e8-f325-4b9e-bf6c-5eea494603aa\SteamLibrary\steamapps\common\Sonic Hedge Mod Manager\
    Process Level: Administrator
    GameInstall: Sonic Generations (2011)
    Update Status: Up To Date

Exception:

    Type: ArgumentNullException
    Message: Value cannot be null.
Parameter name: path1
    Source: mscorlib
    Function: System.String Combine(System.String, System.String)
    StackTrace: 
       at System.IO.Path.Combine(String path1, String path2)
       at HedgeModManager.Linux.PatchRegistry(Game game) in C:\Users\User\source\repos\HedgeModManager\HedgeModManager\Linux.cs:line 48
       at HedgeModManager.MainWindow.<SaveConfig>d__56.MoveNext() in C:\Users\User\source\repos\HedgeModManager\HedgeModManager\UI\MainWindow.xaml.cs:line 1139

Expected Behaviour

The settings should save, and I should be able to start Sonic Generations with the mods I've selected.

Additional Context

I'm using Fedora Silverblue 40, and the latest versions of Bottles, HedgeModManager, and Steam. SonicGMI is not installed. My system is fully updated, and exceeds the minimum requirements for Sonic Generations as well as the mod I was trying to use, the Unleashed Project.

Do you have a .steam directory in your home directory and is Bottles given permission to it?

[DizzyDaisy909]

Do you have a .steam directory in your home directory and is Bottles given permission to it?

It's not in my home directory, I dug around and found it in ~/.var/app/com.valvesoftware.Steam/.steam .

After adding it as a directory with Flatseal, the problem persisted.

It also opens a second window in the top left that I can't move, as seen in the video.

[thesupersonic16]

Right now HMM only works with a normal Steam install. Could you try adding a symbolic link to ~/.steam targetting your ~/.var/app/com.valvesoftware.Steam/.steam and see if HMM works as expected? If it works I could try having HMM look for the path.

As for HMM opening another window, I have never seen this happen before.

[DizzyDaisy909]

Doesn't seem to work.

I'd try the normal Steam install but Silverblue only lets me use Flatpak, AppImage, and anything from their store. It's idiot-proofed to a fault, it seems.

[thesupersonic16]

I will have to make a custom build later, could be HMM not following links.

[DizzyDaisy909]

It could be that... sorry about this, and thank you for thinking about a custom build.

[thesupersonic16]

Remove the symlink you just made and then try this build.

[DizzyDaisy909]

Same result sadly.

[thesupersonic16]

When you installed HMM did it automatically detect all your Steam games, or did you manually add them?

[DizzyDaisy909]

I had to manually add them.

[thesupersonic16]

Give this a try.

Same issue sadly.

Hang on! It works in Lutris. I was able to save my mod layout properly and without issue. It stopped recognizing where I installed Generations so I'm gonna reinstall it properly and report back what happens.

[DizzyDaisy909]

It works!! What I did in Lutris was just add the EXE with the default settings.

[thesupersonic16]

Maybe there was permission issues set for Bottles. Which exe did you use with Lutris? Could you check all the ones sent here including the latest exe from the GitHub release?

[DizzyDaisy909]

The latest one on the Releases as well as the two posted here work fine in Lutris and don't work in Bottles. They have the same permissions according to Flatseal.

Both use the default permissions other than the extra folders Lutris needs.

[thesupersonic16]

Interesting how Lutris works. Does Lutris automatically install .NET on its own? Also not sure how the release HMM was able to work since you are using the flatpak version of Steam. Maybe it is creating its own symlink.

[DizzyDaisy909]

Sorry for not seeing this. Yeah, Lutris installs .NET on its' own. I'm just as in the dark as you are though about how this is working. I'd examine further if I knew how to do that.

[DizzyDaisy909]

Update! The 2nd modified version works better than the normal exe. Both work but the unmodified one works maybe 75% of the time. Dunno what that's about but that's what's happening. That 25% of the time, it throws the same mscorlib exception as before.
