Inspiron 16 plus7620 - usb connected wired mouse intermittingly freezes

One month old computer

System: Dell Inspiron 16 7620 - 12 gen i712700H  (2022)  32gb RAM GTX3060. Windows 11 Home.

Problem:  USB wired mouse intermittingly freezes. 

• problem noted from day 1 after setup of computer.
• random. intermittent - can be a couple of seconds to a minute. Occasionally indefinite freeze. Mouse works again  when mouse is unplugged and plugged back into USB port - works again until the next freeze.
• can be on any program. sometimes when closing a program eg - chrome browser or starting a program. or randomly whilst in MS Word or any program. Often coming out of sleep mode produces the longest freeze -  sometimes indefinite until I unplug and plug back into USB port.
• tried  different wired mouses (Logitech brand) indifferent ports, including connecting to USB on a HUB that is connected to thunderbolt port. You name it, I have tried the different permutation. Mouses work fine on other computers.
• strangely - a Logitech wireless mouse connected wirelessly by the dongle to the USB port does not appear to have the problem.

Troubleshooting attempted

• searched internet. updated drivers -  both windows and  through Dell Support Assist.
• tried turning off windows power saver/sleep options in power settings, in USB - mouse "properties" in Control panel device manager.  Each has been returned to its original state.
• tried updating mouse drivers - incidentally windows 11 always revert back to "HID-compliant Mouse" in Device Manager
• Dell online tech support through Support Assist:  spent  3-4 hours with technician, including the technician logging in remotwly, taking control of my computer - uninstalling windows updates and reinstalling. Uninstalling and reinstalling drivers. Told him problem existed at day 1 before any updates occurred. He also disable Dell  Client Management Service I think. Was suppose to fix the issue but it did not.
• went to this thread:  https://www.dell.com/community/SupportAssist-for-PCs/Intermittent-freezing-for-several-seconds-at-a-time/td-p/7622431/page/4   -  so disabled Dell Support Assist Remediation in Services App - thought it worked. Looked promising. The next day, today, I am writing this because the issue is still there. 
• I have the latest SupportAssist v3.11.4.29 installed

Anyone with this computer Dell16 plus 7620 with the same problem?

Potential issue:

1. Is it an issue with integration of i712700H/motherboard? Defective motherboard?
2. Dell software/windows power saving issue?
3. stepped CPU power processing issue?
4. Is it to do with the GTX3060 integrated graphics? card? The PCI bus/thunderbolt 4 ?
5. PCI express issue?
6. USB controller issue?
7. Other?

Right now I am at my wits end and considering returning this 1 month old laptop. But I have spend so much time on it and hope that there is a solution so that I don't have to spend more time. 

PLEASE HELP.   If you are Dell associate/technician reading this please help.  Or should I just call Tech support to come in? - not keen as I have spent so much time on this already.
