Cannot run client in dev due to space in my Windows file path

[TelepathicGrunt]

Attempting to run Neoforge with a setup very close to the MDK, I get this error:

Connected to the target VM, address: '127.0.0.1:63513', transport: 'socket'
Error: Could not find or load main class Laptop\.gradle\caches\modules-2\files-2.1\org.ow2.asm\asm-commons\9.5\19ab5b5800a3910d30d3a3e64fdb00fd0cb42de0\asm-commons-9.5.jar;C:\Users\MSI
Caused by: java.lang.ClassNotFoundException: Laptop\/gradle\caches\modules-2\files-2/1\org/ow2/asm\asm-commons\9/5\19ab5b5800a3910d30d3a3e64fdb00fd0cb42de0\asm-commons-9/5/jar;C:\Users\MSI
Disconnected from the target VM, address: '127.0.0.1:63513', transport: 'socket'

My file path for my project is:
C:\Users\MSI Laptop\Documents\ModWorkspace\CommandStructures-Neoforge

The space seems to be what is breaking the project. Not sure if I can remove that space without breaking a bunch of my other non-mc stuff since I had that path since like forever.

I'm having a similar problem trying to run neoforgedev:

• cloned fork of neoforge to C:\Users\Joseph\Saved Games\minecraft mods\neoforge
• ran gradlew :neoforge:setup
• import project/repo folder into intellij
• Run neoforge client

Results in this error:
