You shouldn't install PVE to a USB stick/SD card. PVE writes a lot and will kill that USB stick in no time, as these are missing the wear leveling and durability. A USB HDD or USB SSD (or M.2 SSD in a USB enclosure) would be fine.

When reinstalling PVE to a new USB SSD/HDD your VMs will still not run, as VMs consists of two things. The virtual disks on your raid5 and the config files on your failed USB stick. And you lost the config files as these were only stored on the usb stick in "/etc/pve/qemu-server/". So in case you didn't backup the VMs or "/etc/pve/qemu-server/" folder you would need to create new VMs from scratch, matching the old VMs configs s close as possible and then add the virtual disks of your old VMs to the new VMs.
