BootLoaderError failed to write

Hi, After failing to install multiple time, i finally got the installer to run by editing the install command on the grub screen to target my USB drive via UUID instead of label.
Now im failing in the install itself right at the end, with an error about writing the bootloader configuration, and a message saying the drive wont be bootable.

This is the log:
