Heinrich,

Martin Blumenstingl has written a driver for the 8723ds chip. It has been merged 
into the wireless-next tree, and will be in mainline kernel 6.5. In addition, it 
is available at https://github.com/lwfinger/rtw88.git.

Please try it to see if it files your crash problem. Several users of rtw88 have 
reported success.
