Thnak you so much Ed for the guidance. I was able to download the Fedora 34 distribution, removed the openjfix and openjfx8 packages, plus the two files that appear in the error message
Error: Transaction test error:
  file /usr/lib/.build-id/c7/dcd663e38adaac7a2d8d137c46f337ab5543cf from install of openjfx-3:11.0.9.2-4.fc34.x86_64 conflicts with file from package openjfx8-8.0.202-26.b07.fc34.x86_64
  file /usr/lib/.build-id/e6/010f9c606facd1495fb823e9e767752537712b from install of openjfx-3:11.0.9.2-4.fc34.x86_64 conflicts with file from package openjfx8-8.0.202-26.b07.fc34.x86_64
However, when the command to instal is given the above error appears repatedly, even after rebooting. Is there some kind of chace to clear?

I'm not familiar with openjfx or openjf8 and I've not see this sort of error before.

There are several things you can try.

system-upgrade download --refresh --releasever=34 --allowerasing

or

system-upgrade --exclude=openjfx --exclude= openjfx8 --refresh --releasever=34
then upgrade them after the system upgrade has completed.

or

You can remove/erase those two packages, do the upgrade, and then add them back after the
upgrade is complete.
