That error says there was a timeout trying to communicate with org.freedesktop.fwupd. That resource is controlled by the fwupd project. This is likely an issue that needs to be reported to them, but let's get some basic information.
First, run this to see what the output is:
systemctl restart fwupd.service
If there isn't output, that's good, it means it was successful.
Then, run this on command line:
fwupdmgr update
If that shows any errors, copy and paste the output.
