MacBook Air 2020 / Thunderbolt 3 dock / Catalina 10.15.6 sound and usb (Logitech unifying receiver) issue

Hi,

I have a 16" MacBook Pro (Catalina 10.15.6) that connects seamlessly to my two ALOGIC thunderbolt 3 docks (https://www.alogic.co/alogic-thunderbolt-3-dual-display-docking-station-w-4k-power-delivery-black.html and https://www.alogic.co/alogic-thunderbolt-3-0-turbo-docking-station-with-usb-c-compatibility-dual-display-4kat60hz.html?___store=default). My Logitech Unifying USB receivers plugged into both docks "just work" and the sound is good.

My MacBook Air *did* work fine with one of the docks when I bought it a week ago. Now it doesn't work with either (I only got the second dock yesterday). When I plug the MacBook Air into the docking station, it cannot see the Unifying receiver until I reboot the MacBook Air, and after reboot it always puts the docking station sound output at 100% and full left balance.

The MacBook Air is also crashing a lot (the tasteful Mac version of the Windows Blue Screen).

I have not changed any MacBook Air settings or installed anything likely to cause this. I have installed some Apple updates though..

I have reset NVAM and SMC, and diagnostics come back clean.

Does anyone have any ideas please?

Thanks a lot, T.

Ok, fixed this! Just incase it helps anyone, the solution was to do an Internet Recovery. This got everything running perfectly with no data loss, and with all my applications working fine.

Go to "If you can't start up from macOS Recovery" on this page: https://support.apple.com/en-gb/HT201314

No idea if a macOS Recovery will do it, but I figured it was working, but then some update trashed it, so I'd just jump to latest rather than re-install the same updates.

Ok.... not fixed... the above solution worked for a couple of days, then the problems started again, together with random system crashes (with and without dock).

I tried updating to Big Sur, which made things slightly better, and now and again everything would work well for a couple of days, but this issue isn't going away...
