I tested this with the 5.10.18-1-MANJARO kernel as well as the 5.9.16-1-MANJARO kernel. Both exhibit this behavior. My CPU is a AMD Ryzen 7 3700X.
I looked through the callstacks of both kworkers and I found that cfg80211_pernet_exit as well as rtl8169_runtime_suspend both use rtnl_lock. I was wondering if this lock could be related to my problem of hanging processes, so I recompiled the linux510 package (the 5.10.18-1 version I have installed) with lockdep enabled, which should help identify problems with locks. It does a selftest at startup which I included:

I am not sure, if this is really related to my problem or if this is a red herring, but it does not seem ideal. In any case, I am not sure how to debug this problem further. It appears every time I restart my computer and the hanging processes cannot be killed, which means I cannot shutdown my computer normally.
