I have a 2020 iMac 27-inch running Sonoma 14.6.1 and just in the last week the mouse seems to be freezing up then jumping around constantly. I am using a new logitech USB mouse that I just bought because I figured my old mouse was just getting old. But, the problem still exists. It is driving me crazy. This pretty much started when I installed the latest OS update.

Hello,
In Disk Utility>View, select Show all Devices, highlight the top left entry.
Run Disk First Aid on all items in the left panel, from top down.
Are you running any VPN, Anti-Virus, or Cleaning apps?
We need to see what all is running, a report from this will not display any personal info...

OK, We either need more clues that etrecheck could provide, or...
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?
If not working in the new Account try reinstalling the OS.
Try the following:
1 - Reset NVRAM or PRAM on your Mac - Apple Support (for Intel Macs) and Mac startup key combinations - Apple Support (for both types)
2 - How to reset the SMC of your Mac - Apple Support
OK, can you try another cheap USB Mouse?

I did the Disk Utility First Aid. All is well with my disk. The problem of my mouse connecting and disconnecting constantly is still a problem. This just started and I have done nothing different to my computer. It worked perfect a week ago. I am not comfortable downloading a program as you suggested.
I have done that. I bought a really cheap one first and it did not fix the problem. Saturday I bought a logitech and the problem persists.
USB mouse just started freezing and jumping around.
