I have the same problem when I create a usb stick of Fedora 32 but only on
some newer machines.
I don't think it is a bug but this shows how to fix it:
https://bugzilla.redhat.com/show_bug.cgi?id=1768498
Had to access the stick offline on another machine, then , I edited the
/etc/lvm/lvm.conf file and changed these two parms to these values:
external_device_info_source = "udev"
fw_raid_component_detection = 1
it now boots fine on all the machines (one that hung on the Monitoring LVM
and ones that did not)
