TUXEDO Book BC1507 random shutdowns

I have a TUXEDO Book BC1507 and since October 2020 I’m suffering random shutdowns.

When I initially contacted Tuxedo support they said they essentially had no idea what this could be and then when I reported this on their Tuxedo Control Center GitHub (Random shutdowns with v. 1.0.13 and kernel 5.10 · Issue #117 · tuxedocomputers/tuxedo-control-center · GitHub) that is was related to a Firmware bug in interaction with the keyboard. The issue was closed claiming a new firmware update was available but the one they suggested to install doesn’t carry any update and support is not very active on this (maybe because this is not one of their latest models).

I’m wondering if anyone using manjaro has this laptop and has managed to fix this or has any idea about it.

In case this might be relevant I’m running a 5.15.12-1-MANJARO kernel and version 1.1.0 of Tuxedo Control Center, but have been experiencing this with previous Kernel / TCC versions.
