Iray won't work if not switched to as the first action after running DS

Hey guys!
As they used to say in this kind of forum topics two decades ago, "subj" :)
So yeah, recently my DS behaves weirdly with Iray. If I don't switch to Iray preview as soon as I launch DS, it won't work later. Even if the first action after launching DS is clicking File -> Open menu (then suddenly remembering "Oh no, gotta run Iray first!"), Iray won't work. The log file says something like "Iray can't find a rendering device" in this case. But if the first action after launching DS is switching to Iray, everything goes fine later: scene opening, editing, switching between scenes, rendering, and so on. Weird, huh?
What could it be? Did I break something in DS?

What is checked in Render Settings > Advanced > Devices?
CUDA 0 - NVIDIA GeForce RTX 3090 (WDDM - Display)
So you can render fine using the GPU, but just not using Iray preview.
A Screenshot of Render Settings > Advanced would help...
No, rendering won't start as well. It's like DS can't find the rendering device.
I've started DS and made a different first action instead of turning on Iray to get a fresh log. Here it is:

Sure, here it is.
Which Nvidia driver version are you using?
Why the "Check GPU driver version" is not checked?
512.96. I rolled back to it from two versions of 516s. Can't remember what was wrong with those exactly, but something was.
The Check GPU driver version was unchecked when I was looking for a way to return Iray to its proper functioning. One time it seemed like it helped, but then it turned out that it actually did not. And I just left the checkbox unchecked.
It would help to see what else is in that log. Do not copy it to the message area, but attach the txt file to your post with the "Attach a file" above the "Post Comment" button.
Sorry about log-posting before. Here's the full log file. I hope you can see more in it than I do because to me, except for that "No device found" part, it's all Greek.
I think the problem is here;
Iray [ERROR] - IRAY:RENDER :: 1.0 IRAY rend error: cuLinkCreate: PTX JIT compiler library not found
Iray [ERROR] - IRAY:RENDER :: 1.0 IRAY rend error: Errors: error : Unable to load library 'nvptxJitCompiler.dll'
Iray [ERROR] - IRAY:RENDER :: 1.0 IRAY rend error: CUDA device 0 (NVIDIA GeForce RTX 3090): device kernel image is invalid (Failed to get function attributes)
But at the moment, don't know how to fix.
Hmm. So it looks like a driver problem, not DS one? Maybe a clean reinstall of the GPU driver will help.
Make sure you have no other Iray related programs, drivers and/or libraries installed, there has been cases when they have been clashing with the version of Iray used in DS and or the installed Nvidia driver version.
Nope, that didn't help.
I guess I'll just have to use DS like this until I eventually reinstall my OS and all the software. That kinda sucks but still not critically terrible.
>>Make sure you have no other Iray related programs, drivers and/or libraries installed, there has been cases when they have been clashing with the version of Iray used in DS and or the installed Nvidia driver version.
I don't think I have any. I use Blender and ZBrush, but I don't think any of them uses Iray.
