Not working with MSI GS76 running Manjaro

[supermarioprof]

I'm not able to have msi-perkeyrgb working, I tried every possible way listed and commented in issues.
My keyboard leds sometimes start working, I can say after a suspend but not always, using the last preset I tried to have it working.

So: it seems the information about the preset is stored, but I cannot start backlighting on my own, it will start quite randomly after suspend.

My system: Manjaro with 6.0.19 kernel (tried also other kernel versions without joy).

any help appreciated!
