HomeAssistant on RaspberryPi doesn't boot anymore - eviltoast

I run my HomeAssistant on a RaspberryPi 4 from a SD card. Two days ago I did a upgrade to the newest version (I don’t remember if it was HomeAssistant or the Operating System) and since then it does not boot anymore.

I connected it via HDMI to a screen and got those errors:

It looks to me that the SD card is corrupted or something. Any idea if I can fix it in any way or do I need to redo the setup from scratch?
