You can supposedly still use 4.5 4.6 on Big Sur if you do the following but I have not tested it on Little Snotch, works fine for personal software and others ...
codesign -dvvv littlesnitch.package name
Save the team identifier
Boot into recovery mode
Open terminal and type the following...
spctl kext-consent add <team identifier>
Reboot into normal user mode and install version 4
The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume.

>> It's not that Bluetooth stops scanning, but it's not scanning as aggressively. So after a few minutes, there will be very high jitter when Bluetooth scans the environment, but it would affect only a single packet. It's easily reduced its chattiness by 99%.
>> I don't have any empirical data to support the claim that Little Snitch has anything to do with it (and I am too lazy to dig further into it), but the reduction in jitter is massively noticeable since Little Snitch. Which means I can now run Catalina with Bluetooth enabled and not have any wi-fi problems.
