CM4 not powered

I have recently taken over an active project that uses a stereopi. I could properly boot to an Ubuntu 22.04 SD card without any problems.
After working with it a little bit, it now does not boot anymore and only the J-PWR and 5V LEDs are on. Neither the PI-ACT or PWR LEDs turn on.
This leads me to believe that there is a hardware malfunction of the stereopi, however i barley touched any of the hardware and mostly worked on the software.

Has anyone had a similar issue? I could not find any info on what to do if the PWR LED does not even turn on.

It looks like CM4 issue.

Could you please try to re-seat CM4 and let me know the result?
