Keyboard keys one stroke two actions

Hi,

I have assembled my FL13 and installed EndeavourOS, which is basically arch linux on it. I have a weird Keyboard issue (German Keyboard btw): When I type the letter p the result is a p an cursor movement to the left, as if pressing the left arrow key; if I press the right arrow key, I get cursor movement to the right plus the letter ß. I have toyed around with various keyboard hardware configurations and layouts. I couldn‘t find a Solution. What could be wrong?

Which Linux distro are you using?
EndeavourOS (arch)

Which release version? Mercury
(if rolling release without a release version, skip this question)

(If rolling release, last date updated?)

Which kernel are you using?

Which BIOS version are you using?

Which Framework Laptop 13 model are you using? (AMD Ryzen™ 7040 Series)

probably a hardware fault.

The Framework keyboards don’t seem to have proper n-key rollover, the arrow keys, p and SS keys are probably sharing lines. might be worth re connecting the keyboard, unpluging and reconnecting the ribbon cabels.
