Perhaps your power system is taking longer to stabilize.

You might try modifying the unloading/loading script to have something line

#!/bin/sh
if [ "${1}" == "pre" ]; then
   modprobe -rv rtw_8822be
elif [ "${1}" == "post" ]; then
   sleep 20
   modprobe -v rtw_8822be
fi

If that still does not work, I have no idea what might be causing the problem. 
If it does work, try halving the sleep interval from 20 sec to 10, etc until it 
breaks again.
