Severe screen glitching

Hello, the issue of severe video glitching on my PC has re-emerged after a few weeks respite. I have now updated to Win 11 in an attempt to resolve the issue, however I am now thinking it has to be a conflict within Adobe software products. This is because it only occurs in Adobe products, and only in certain sections of those products. I have tried every. single. solution under the sun, but nothing has been able to permanently resolve it. The glitching (whole of screen glitching), only occurs in Premiere Pro in the Source window when I'm scrubbing through video, plus the Output (render) window when I make any mouse move at all. It also occurs in the main window of Photoshop when I'm manipulating an image, such as simply cropping. I have worked through every solution Adobe's help team has been able to offer. I have updated and wound back, then updated again, all drivers possible. I have been through the same intense process with nvidia help team, as my PC is running an RTX3070 card. I have also been to the company who supplied my PC and worked extensively with them to find a solution, even to installing a second clean OS on a separate SSD, which does not have any glitching. I seriously think this has to be a conflict within Adobe software, but what it's conflicting with and why, is a mystery. Is there any way of escalating this issue within Adobe please?
