Hello,
My new laptop apparently has a Real Tek R8822BE as the wifi device. The
module loads but I can not bring up the interface or do anything with
it. I think the problem is that the firmware load fails, see below. I
can not find any source for the listed firmware file or any make rules
to build it. Possibly connected, the machine also has an R8822B as the
Bluetooth device (possibly a secondary port on the same device?) which
shows the same error. The problem is not higher up in the networking
stack as eth0 works fine.
Any help will be appreciated.

As the log clearly states, you have not installed the firmware. It seems that
your distro is not up to date. You could obtain it from the linux-firmware
repository, or get it from my GitHub repo named rtlwifi_new. I will send it to
you privately in the next E-mail.
