Magic Trackpad with firmware 1.9.2 keeps disconnecting from iMac (circa Late 2015) running most recent macOS Monterey.
It's so frustrating because I need to hard shut down the iMac each time it happens. Can somebody help? Thanks!
Is there any USB3 interference around, anything generating microwaves at all, phone, tv, microwave, radar, etc?
How may bars does it show?
Long shot...

I've been debugging a problem with my VPN client constantly reconnecting, along with poor WiFi performance. After much digging, I came across an excellent article - although written for Yosemite and iOS8, it still seems to be relevant to Mojave, especially with a newer WiFi chip in the 2018 MacBook Pro. https://medium.com/@mariociabarra/wifriedx-in-depth-look-at-yosemite-wifi-and-awdl-airdrop-41a93eb22e48
The author wrote a program that essentially just issues a command and keeps it enforced. You can try it manually in a terminal window: sudo ifconfig awdl0 down
To reverse the command, type: sudo ifconfig awdl0 up
He gives a great technical explanation, so I won't repeat it here. The command disables a virtual network interface that's used for ad-hoc WiFi by features like Airdrop; I personally won't miss them. So far, I've gone from losing my connection 20 times an hour to being stable for 3+ hours.

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
Thank you for your help. I took time before replying because this problem happens every week or so. I tried your suggestion, the system worked well for more than a week, then it happened again last night. Ugh.
It's difficult for me to test because for me to run any test, the trackpad must be working. So, when it's working, it's working. It's a matter of how to get it to keep working without disconnecting itself again.
You can try a Bluetooth Reset (Monterey and newer)
NOTE: All Bluetooth devices will need to be paired again!
