Have you tried booting an earlier kernel?
Yes. The behavior was consistent across the 3 kernels I had installed.
uname -a
Linux bigboy 5.10.11-200.fc33.x86_64 #1 SMP Wed Jan 27 20:21:22 UTC 2021

If it's not working now on a kernel version that did work before, that
suggests that it's more likely to be a hardware issue than a kernel issue.
Does anything show up in the journal when you plug something into the
ports that aren't working?
Since it appears to be USB3 ports that aren't working, try adding
"blacklist=xhci_hcd" to the kernel command line before booting and see
if that makes any difference. I don't know if that will do anything
since Fedora has that kernel driver compiled in, it's not a module. So
if it doesn't work, try "initcall_blacklist=xhci_init_driver" instead.
