EOS Utility 3 seldom works (Canon EOS R6 Mk II)

[pspdog]

Hello there,
As per title, I'm having major issues with using EOS Utility via USB cable. A few weeks ago, randomly, EOS Utility started acting up in the following ways:

1. When trying to use Live View Shoot, the button does not work - it's not greyed out, but clicking it does nothing. |
2. Sometimes clicking it causes the whole EOS Utility software to shut down
3. When clicking "Download photos and videos" they do not show up, instead I see the following:

This does not ALWAYS happen - all the aforementioned functions SOMETIMES work, but it usually takes a single or multiple resets of either the camera or my computer, or both.
I'm losing my mind trying to fix this as I'm using the functions daily. Here's what I tried:

- Upgrading firmware (didnt help, I'm at the latest available)
- Reinstalling EOS Utility multiple times
- Messing around with EOS utility's options to launch/not launch when camera is connected and multiple others
- Switching around cables (not the issue)
- Using different USBC port of my computer (not the issue)
- Updating all drivers including GPU

Nothing seems to help and I have no idea where to look. Any advice would be helpful.
Mind you, everything worked perfectly up until a few weeks ago, however no notable change was made there either to the camera or to my PC.

Thanks!

“ With all due respect, all of your questions have been clearly answered by me in the past:
- I specified my PC's specifications. I chose the parts but I did not build the machine myself, the shop I've purchased it from assembled it for me. It is a tower. All USB and USB-C ports work correctly with every other device. “

You were asked questions with yes/no answers.  Your responses were vague.

”Did you build the computer yourself?”

Your response was to tell me what type of CPU it used,  If your tower has more than two USB ports , then it most likely uses an internal port expander of some type.  That was the point of asking did you build it.

I suggest that you try every USB port on the tower. There probably should be at least one port that connects directly to the motherboard, not through a port expander.
