Multi-Frame Rendering crash

While rendering with Multi-Frame rendering on imac pro 2017, after effects crashes without saving. This happens pretty much all the time. I like the speed but I always have to keep an eye out in case after effects crashes without me knowing.

 

Specs:
2.3 GHz 18-Core Intel Xeon W

Memory 128 GB 2666 MHz DDR4

Graphics: Radeon Pro Vega 64X 16 GB

I'm on an M1 and I've just turned MFR off. I haven't done extensive testing yet but for now AE seems to run faster with it off anyway

I'm having major problems with MFR while compositing multi-layer .EXR files as well. It works perfectly when I use AE 2021 but once I try to preview using AE2022 I get constant crashes with the window saying After Effects has encountered a problem.

 

This needs to be fixed ASAP.

What version of AE are you using? Is it just a particular set of exr files or all? If you turn off MFR, does AE still crash?

Thanks for responding. It is with ALL .exr files layered in the comp. I have this problem using AE 2022.2.1 and I have had the problem since the new release. Here are my system specs:

 

Threadripper 3960x (24 core)

64 GB 3200mhz ddr4

RTX 3090 (x2)

Msi Creator TRx40

I'm having a similar issue on Windows. AE will take up all the memory I have (even though I have only allocated half my memory), black screen, then crash and ultimately I need to do a hard reset on my computer. The only way to avoid it seems to be turning off MFR.

3.8 GHz AMD Ryzen Threadripper 3960x 24-core

That's really strange. Any chance you're able to package up a project that causes this to happen and send it to us? (mfrbeta@adobe.com)

I believe the crashing may have to do with using EXR image sequeneces. Perhaps AE needs to cache more than the allocated amount since EXRs are such heavy files? I converted my EXR image sequences to Tiffs, turned MFR back on and didn't have any crashing and AE didn't allocate more memory than the amount I had set.

And AE doesn't crash with MFR off? All comps or specific comps? Which beta build?
