Can't connect to WiFi on Big Sur Beta6

[seungjunProgramming]

alpha3 worked fine, but alpha 4 doesn't work on Big Sur beta 6
Also Makes AppleIntelBluetooth unstable

[usr-sse2]

It works on beta 6, although it's not stable. I know an issue with WPA* networks and am working on a fix.
What authentication is the network using? How it 'can't connect'?
Please enable debug logs with

sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport debug +AllUserland +AllDriver +AllVendor

and then show the output of the following commands:

sudo dmesg | grep "itlwm\|Black80211"

log show --last boot --predicate 'sender="IO80211Family"'

sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport logger 

The third command should be running while you are trying to connect to a network (it shows the log in real time), and the first and the second should be run after trying to connect (they show the history).
