There are two workarounds.

1. Copy the 0.27.x firmware from my download site and install it using the
following:
wget lwfinger.com/download/rtw8852b_fw.bin
sudo cp rtw8852b_fw.bin /lib/firmware/rtw89/.

2. Implement the driver found at https://github.com/lwfinger/rtw89.git.
That version can handle version 0.27.x or 0.29.x of the firmware.
