Short description of error
Blender crashes and fail to render. This happens on multiple files and not file dependent. Sometimes once it goes through then it will start working on other blender files too.

Exact steps for others to reproduce the error
Click on the file, hit "Rendered" icon in Shader tab . Wait for 5 mins and nothing happens. Info stops at this screen. Clicking back to Material Preview or Solid, the software will crash.

Hi, thanks for the report. I think this happens for the first time only. Did you wait till the end of compilation of the kernel?

It does take quite a few minutes to do. You can also see it in your second image: "Loading render kernels (may take a few minutes the first time)"

The problem is I've waited more than 10 minutes and it doesn't have any countdown to when it will end. As soon as I hit any other render view, it will instantly crash my Blender.

It's now back to working and it works instantly like within 30 seconds even If I close it and reopen it. But the problem is this happens every now and then and It's like opening a box of chocolate, you don't know when it will work and when it will fail. @PratikPB2123

Hey! Something New

I've noticed that if I turn on Motion Blur (off and on), the problem can be spotted occur in the blender render when I try to render a single frame. Not sure if this gives a clue?

p.s it was originally off

Another issue encountered which is that it starts to appear in rendering window. No Eestimated time. It's fine during window render, but somehow when i press render animation, it's loading again

I think it's working now if i wait a bit longer. (i'll continue to monitor) but i guess it's because it doesnt have a Estimated countdown, i feel like the software is freezing and doing nothing?

OKi, thx getting back.
Not sure if compilation time can be estimated well.
This might be improved (but would not be considered a bug).
I'll archive this for now (feel free to comment again if you come across the case it actually never works -- even after waiting long enough)
