I think I've found a solution for now with my MBP M1 2020.
After the Monterey upgrade, my 7 in 1 USB-C Hub by WKD stopped all USB connectivity (mouse, keyboard and external storage etc)
However I had a small USB-C to HDMI Adapter 4K, Multiport Type C adapter with USB 3.0 and charging port I was using on my iPad Pro. I plugged this into one of the USB-C ports on my MBP, used a USB C to USB male adapter for (Acessorz _ on Amazon UK) to connect my 7 in 1 USB-C Hub into and all the USB ports are back working again.
PS. The charging port is also working too.
I'll try and give the descriptions below of what I'm using.

I Hope this helps someone out, I've been at this for hours and been totally stuck.
Hi,
After upgrade to Monterey, latest public beta (21A5506j), PD over usb-c from my monitor (Philips 346P1CRH/00) doesn't work as well.
Apple please help!
Looks like most comments here are with MacBook and the M1. I have a been running a duel monitor set up with my MacBook Pro (intel) for years without issue on the MacOS Beta program. It wasn't until I just upgraded to release 8 that the monitors are no longer detected. I have not been able to find a workaround so any help would be appreciated.
PD (Power Delivery) over USB-C also stopped working on my MBP 2018 after updating to Monterey (12.0.1). I use a Philips 346P1CRH. Everything was working flawlessly with Big Sur.
