Quick update, it'll need to be another day (hopefully tomorrow), but I'm working on getting a build made and tested. I had to install the Linux SDK for Unreal and I have to work in just an hour so I won't be able to get this out tonight. Sorry again! I'll try to get it done ASAP.
Heya! I know it's been, oh god, two months, but I figured out why it wasn't compiling. Turns out even though I checked Linux support when installing UE5, it never actually installed the SDK..
Got that working today, and apparently a plugin I use all the time also doesn't work with Linux builds, so I'll be working on fixing that, either by getting the plugin to compile for Linux or by replacing the plugin's code. So sorry for the wait, been a hell of a few months for me.
