My Raspberry Pi 4B frequently freezes and becomes completely unresponsive (no SSH, black screen on monitor). The only way to recover is to physically pull the power plug and reboot. I'm booting from an NVMe SSD connected via USB through a powered USB hub.
Hardware setup:
Samsung SSD 960 EVO 250GB inside an NVME enclosure . The output of this enclosure (USB) is then connected to a powered USB hub. The output from this hub is then connected to my Raspberry Pi's USB port.

Both the USB hub and Pi receive power seperatly. (The Pi using its official power brick at 3A 5.1V)
In my journalctl, this happens moments before the Pi bricks:
Feb 06 07:17:02 raspberrypi systemd-fsck[403]: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
Feb 06 07:17:02 raspberrypi systemd-fsck[403]: Automatically removing dirty bit.
Feb 06 07:17:02 raspberrypi systemd-fsck[403]: *** Filesystem was changed ***
(Not sure if it has anything to do with it.)
The Pi works fine after rebooting for +-1 day, and then it (soft)crashes.
Am I missing something here? Did I buy the wrong USB powered hub? I know the Raspberry Pi 4 has its problems with NVME SSD boot drives, but I'm really trying to get this to work, permanently.
Thank you for your help!
