Where does that module come from?

I don't find any reference to the string 'rtl88x2bu' in my currently
configured/available source repositories (current Debian testing and
stable), so my reflex is to suspect that this is a third-party module
you've gotten from somewhere outside Debian.

If that's correct, most likely that module is not compatible with some
change that's included in the kernel (or build chain) in question, and
you'll need to either update it from where you got it, or remove it.

If you want to troubleshoot beyond that, I'd suggest starting by looking
at the log file indicated in the error message; there's not a lot we can
do to figure out the cause of the build failure without access to that log.
