I have compiled as self-contained, however I missed some configs to make sure that all native binaries were included in the final executable. I've made a new release recently (https://github.com/JustAman62/undercut-f1/releases/tag/v3.0....) which should resolve this issue.

As noted in https://github.com/JustAman62/undercut-f1/issues/3#issuecomm..., I think there's still more work to do to make the single-file executable work properly on Linux, due to the intricacies of the native Skia libs.

True single file static executables should now be working in the latest release.

Can confirm, works perfectly now.
