Consistent viewport lockup with multiple drives

[Alacrious]

I am using Ae to process and batch photos for photogrammetry, they are not excessively large and are approx 4k.  I am running into issues where viewports are entirely unresponsive after the first or second frame updates.

Ae will freeze the viewport, and no amount of purging, changing the cache folder to another SSD, manually rebuilding the file, driver updates, changing preview settings, reformatting a fresh W11 entirely (yep), or moving the entire project directory around to different non-C:\ SSDs fixes this.  It becomes responsive when I move the entire project directory AND source AND cache on the main M2 drive (C:) it acts normally. 

I have tried a mixture of project + source + cache, mixing it through all my drives, and if the project and cache are not somewhere on C, it will within the first minute, freeze, lock up, forcing me to restart, where it will freeze after the first minute again.  Funny enough, if I check the disk cache in Ae, it will udpate for 2 more frames, then freeze again.  Check attached videos for examples of this.

After effects is the only application that does this, and the files are read in well in Cinema 4D, Houdini, Agisoft Metashape, windows image preview, etc and I can scrub it back and forth and get a viewport preview, and it will not fail. 

Windows 11
Threadripper / 128GB / 2080ti / 1TB M2 boot / 4 Samsung 1TB 860 (no raid)
After Effects 2023
All drives NTFS and no more than 2 years old.

How to reproduce: Have anything not on C
Expected result: Be normal

I will gladly provide an entire project directory.

Hey there! It's been a while, how are you doing? 😄

Can you give us a little more info about your workflow? Are you pulling in image sequences and adding effects?

[Alacrious]

Heya, long time no chat!

Zero effects, images are pulled in individually, sequenced in the timeline, and then matted to the layer underneath when Im done pre-masking.  Nothing is added to them at all.  When I moved a singular mask point like in the videos shown, the viewport locks up until I check the preference panel where I get another frame of updates.

I have found some extremely weird interactions on top of that just playing around just now.

If I click outside of Ae (desktop, additional window, etc), then click back in, it updates the viewport.  I can do anything, click out of it, click back in, and the viewport updates.  I have ZERO plugins or extensions installed, this is an entirely vanilla install.  I can reproduce this anytime, but it looks like I cannot add additional videos to the above post.

Re-bumping this because it continues to be an issue.

Booting in safe mode still locks up the viewport, another re-format has not fixed this.  It also now will not refresh the viewport when using simple solids.  Please advise on any sort of logging or documentation I could submit to help this along.

Are you still having the issue? Let us know.

I am moving this thread from Bugs to Discussions for now.

Thanks,
