Mac Forge 1.18.1 crashing on launch, bootstraplauncher

[WolfBV]

Describe the bug
When attempting to launch a custom modded instance of Forge 1.18.1 with forge 39.0.36, it crashes and the console shows
"ps stderr: Error: Could not find or load main class Support.gdlauncher_next.datastore.libraries.cpw.mods.bootstraplauncher.0.1.17.bootstraplauncher-0.1.17.jar:.Users.user.Library.Application
Caused by: java.lang.ClassNotFoundException: Support.gdlauncher_next.datastore.libraries.cpw.mods.bootstraplauncher.0.1.17.bootstraplauncher-0.1.17.jar:.Users.user.Library.Application"

I created an empty Forge 1.18.1 instance and launched it with both Forge version 39.0.0 and 39.0.44, which crashed with
"ps stderr: Error: Could not find or load main class Support.gdlauncher_next.datastore.libraries.cpw.mods.bootstraplauncher.1.0.0.bootstraplauncher-1.0.0.jar:.Users.user.Library.Application
Caused by: java.lang.ClassNotFoundException: Support.gdlauncher_next.datastore.libraries.cpw.mods.bootstraplauncher.1.0.0.bootstraplauncher-1.0.0.jar:.Users.user.Library.Application"

To Reproduce
Steps to reproduce the behavior:

1. Create an instance of forge 1.18.1
2. Launch it

Expected behavior
To launch 1.18.1 Forge instances.

Possible Solutions
gdlauncher is located in an Application Support file in /Users/user/Library/Application Support/, the issue mentions Users.user.Library.Application, that could be the problem?

Operating System:

• OS: macOS Mojave
• Version: 10.14.6
• Java Version: 17
• Minecraft Version: 1.18.1
• Mod Loader: Forge

Additional context
Deleting the gdlauncher and gdlauncher_next folders and the gdlauncher app, then installing 1.1.21 again did not fix this. Going to try an older version of gdlauncher next.

gdlauncher v1.1.18 works, gdlauncher v1.1.19 doesn't

I recommend you version 1.1.21

[WolfBV]

I am using 1.1.21

Ah yes I See. That spacing issue from MacOS again.
A workaround would be to move your data to a path that doesn’t has a space in it.
(Macs Application Support folder messes whit it)
Will go fix it soon

I have this same issue on arch linux with gdlauncher 1.1.21.1 for forge in minecraft 1.17 and 1.18 instances. If it is forge it wont launch and fails but fabric runs fine on both.
