Roto Brush (any version) crashes every time I try to Freeze

1.) After Effects 2025.3 (Build 4) and After Effects Beta 2025.3 (Build on April 09, 2025).
2.) Win 11 Pro. Version: 24H2. Build: 26100.3476
3.) Take footage of any kind. Use Roto Brush 1, 2, or 3 on any length of footage, be it a sequence, MOV, or other wrapper type, and after masking, save the roto by clicking "Freeze." 
4.) Expected result: saving the matte, so After Effects doesn't keep using computer resources to endlessly re-propagate mattes it has already made. 
*Actual result: After Effects crashes, every single time.

The Roto Brush 3 is pretty good at maintaining animated shapes, but it doesn't save when I click "Freeze." I am working on 4K footage, which I shifted from uncompressed/RAW to JPEG files. I used Roto Brush 3 on a 110 second clip. It did rather well, and I did some cleanup, and after saving my project, I went to "Freeze" the Roto Brush, so it would preserve the shapes.

I have tried this multiple times, including with Roto Brush 2 and 1 (nowhere near as good), and every single time, After Effects 2025.3 Build 4, will hang and then crash. It doesn't matter if I only do five seconds, of my 30 FPS 4K footage, the app will crash the moment I click on "Freeze."

I have added the OpenCL and OpenGL Compatibility add-on from the MSFT Store, and that didn't help either. Yes, I have the latest Studio Driver for my NVIDIA RTX 4090 with 24 GB of VRAM, and this still crashes. I am running Win 11 Pro, but from the community boards, it appears the OS is not the issue, the software is. 

As for my PC build, I tried this on both an ASUS and Gigabyte motherboard, both using 256 GB of DDR4 memory, with all "hard" drives being NVMe. The OS is on its own NVMe with the Adobe software, the raw footage is on one NVMe, the cache is on a separate NVMe, and the output is on a separate NVMe. 

All of this is on a 64 core AMD Threadripper at 3.7 GHz (series 7). This is on After Effects 2025.3 (Build 4), as well as After Effects Beta 25.3 (as of April 09, 2025). 

I gave the cache 600 GB, not that it used it all, or all the RAM. I've been using Adobe for over 20 years. I've used the roto brush before, and didn't have issues with the Freeze function, or in refining the matte, etc. Ever since After Effects 2024 up to now, well over a year, this problem has persisted. However, I don't want to have to use an inferior iteration to get the work done, because it just means a lot more cleanup.
 
I have optimized the heck out of this by exporting the video as a sequence, so there would not be any concerns over GOPs (not that there would be on uncompressed, INTRAframe video), and made the Roto Brush its own project. I am not using any filters or effects, just the Roto Brush, that's it. 

After Effects simply crashes every single time. 

What is worse?

After having made a refined/cleaned up matte, the only workaround I can come up with, is to render out the sequence as either another sequence or as video, with the selection as an alpha, or as RGB + alpha that I later apply an effect to cover with a solid. 

Yet, despite every frame being cached, when it goes to render, it propagates ALL the frames again! You can imagine, on a 110s 4K clip, how agonizingly slow that is, even on a rig like the one that I am using. It can still take up to 2+ hours using the GPU, or up to 3+ hours using only the CPU. 

There has got to be a way to fix this with a patch. Roto is integral to using After Effects, and one of its KEY functions does not work, at all, and there is no comment about when it's going to be fixed. This was shipped knowing it was broken. The only recommendation is to use the earlier roto brush v2 or v1. While it may not crash for some users, it doesn't matter which Roto Brush version I use, I can never "Freeze" the matte so I can keep working with my comp. It crashes every single time. 

This has been an issue since AE 2024. We're now in Q2 of 2025, and this is still not fixed. 

Why is this important to me? I'm doing a series of shows shot poorly on chromakey, and roto is critical to extracting decent mattes. I've got over a  dozen shows, each 26 minutes long. Can you appreciate why I'm tearing my hair out? No, sub-contracting overseas to roto all of this is not an option. This should simply work.

Can we please get an update? 
Thank you.
