Graphics panel not loading anything

I am an IT supporter, working on an issue we're facing with Rush on all company machines, and I have hit a wall.

The issue is, that graphics in the lefthand panel is not loading at all. It will show the loading animation for about 10 seconds, and then show the background and nothing else (See the attached picture 1).

The audio panel, which I assume is loading the resources from the same pages does not have this issue (See picture 2). Additionally, if we import .MOGRT files manually, we can use them no issue (See picture 3).

The issue is only faced on company machines, and not on the same hardware, but installed with a Windows installation outside of the company environment. However, I have dug through our Group Policies without finding anything blocking this, or Chrome/Edge processes that may be related. We have also attempted turning off the Windows Firewall+running on a non-company wifi, and the issue persists.

Additionally, I have run the uninstall tool several times, both by just removing the software, but also removing CC and resetting settings+any other option available. The issue is also present on completely fresh Windows installs at our company.

Additionally I have attempted to move files from a functional non-company PC, to the company PC, to ensure that all files are present, and this also did not solve the issue. The anti-virus/Endpoint Protection has also been checked, to see if it puts files into quarantine, which it does not.

I have also attempted a few smaller changes, like clearing cache in both browsers and Premiere Rush, but without the expected results.

Am I so lucky that someone has experienced something similar, and have a solution? Or does anyone have an idea as to where I should go next in my troubleshooting?
