Monitor or possibly cable, depending on how you did the swap.

See the suggestions on issue #409.
What's peculiar here is that one monitor is responsive, one not. I assume you've tried swapping them.

@rockowitz sorry for the late reply, yeah I swapped cables and ports on the graphics card, but the same monitor (same SN) was detected as invalid.
The suggestions from #409 did not change anything, it looks the same with and without the sleep options.

I've also factory reset both, but did also change nothing.

I'd say you have your answer, though if you swapped the cable along with the monitor it could be that.

Then monitor :/ As I used the same port and cable which worked for the other monitor.

Okay reopening this one.
I just connected the monitor that didn't work via HDMI and now it got detected and I also could set the brightness. But while one (the one that was working previously) was connected via DP and the other (that didn't work) via HDMI, the one connected via DP was detected but I couldn't set its brightness.

After I disconnected the HDMI cable and connected the 'non working' one via DP, it still was detected, but I'm now still only able to set the brightness for the 'working one'.

EDIT: now I realized that I need to specify the display number, so currently I can set the brightness for both when I either specify -d 1 or -d 2, I'll see what is the state after I reboot.

Okay, for whatever reason it just works.
So for future reference: The 'solution' was to connect the nonworking monitor via HDMI and then running ddcutil detect, afterward it just works 🤷🏼♂️
