Lakka 3.7 RPi4 64 Bits => GameMode unsupported and Vulkan error ?

Lakka stays on Logo and running verbose mode shows:

Fixed the gamemode error adding the line to the config, but still having problems with Vulkan it seems.

Line to fix:

gamemode_enable = "false"

is gamemode on by default? I did not experience this issue on rpi400. vulkan on rpi does not work with all cores.

I didn't have the option on the retroarch.cfg, I added but still have issues, so I decided to fully remove it and let it create again. Now it's working fine.
