mdadm RAID5 array became "active, FAILED" and now no longer mounts

Today my RAID5 array status from mdadm --detail /dev/md0 became active, FAILED (I have mobile notifications setup) Most of the files were present but some were missing. This happened before and I solved it by rebooting the machine (I think the status was different tho) No luck this time, now the RAID no longer works Here are some details about my setup:

mdadm --detail /dev/md0

unused devices:

The drives seem healthy, no SMART issues I tried running mdadm --assemble --scan but I get

mdadm: /dev/md0 assembled from 0 drives and 4 spares - not enough to start the array.

mdadm: failed to RUN_ARRAY /dev/md0: Invalid argument
mdadm: Not enough devices to start the array.

The exact same for mdadm --assemble /dev/md0 /dev/sdb /dev/sdc /dev/sdd /dev/sde and with/without the flags --run --force I'm running Ubuntu 24.10, everything up to date including kernel 6.9.9 What can I do to recover my array? I've read about doing

mdadm --stop /dev/md0
mdadm --zero-superblock /dev/sdb /dev/sdc /dev/sdd /dev/sde
mdadm --create --assume-clean /dev/md0 --level=5 --raid-devices=4 /dev/sdb /dev/sdc /dev/sdd /dev/sde

but I'm afraid that if I lose my data I also break any other recovery attempt.
