I don't know why it does that, but I know where it comes from : newer versions of the toolchain made the bootloader compilation crash. I don't know if the bug is in the toolchain or in Upsilon
A temporary fix I use is to downgrade the toolchain. On Arch Linux, you can do that manually or use the downgrade AUR package (with a graphical interface).
I didn't test every toolchain version (because it is long to download every version), but I know it is working on 11.3.0 (which I use).

Can this version be used in Github actions build ?

I preferred falling back to Omega's bootloader, this issue should be investigated further. I'm not qualified enough to do it though
