Signal_Handler: Caught Memory Access Violation

[obiwan51]

Hi guys,

I'm having a problem when trying to run the project. I'm getting a Signal_Handler: Caught Memory Access Violation
Running on an AMD Ryzen 7 3800X, 32Gb RAM, AMD Radeon RX 5700XT, Windows 11.
The console shows:
` J:\ltheory>python configure.py run

any help would be very appreciated.

@obiwan51 If you try pulling the latest main branch, I'm curious if this has been fixed? We recently merged some fixes to the Windows build.

hi @dgavedissian
I still have the same issue, if I comment out the NYI (not yet implemented) code from Bullet.h line 77 I can start the engine but it's blank, see below. I think is because of the architecture of the processor, I tried build it on a Intel i5 and it worked but on my AMD Ryzen 7 doesn't.

[dgavedissian]

I think some of the shaders might not be playing nicely with the AMD OpenGL driver. I've seen similar issues in the past myself as well.

On the Intel i5 machine, did it use an integrated Intel GPU or did that computer have NVIDIA graphics as well?

[obiwan51]

It has an integrated Intel HD 530 GPU. It could be the shaders also because I get a lot of undefined variable from the shaders when it runs. I'll test more and see where I can get with it.

@obiwan51 Someone recently hit the same problem and found a workaround which just got merged into main. If you try the latest build, it should work now!
