Rendering Error "After Effects warning: Could not open the file ... on cache disk"

[GHunsburger]

I get the following error(s) everytime I render my project... 

After Effects warning: Could not open the file 'F:\AE\Adobe\After Effects\22.0\Disk Cache - USERNAME.noindex\9c\9c68e7c7-378e-c09c-69ce-e77dd9536bde.ADBE ICV.B300E02.AAAAAI8AmAA=.aecache'.

I get sometimes 8 or even 20 lines of this pointing to different .aecache files.

I still get my .Mov file at the end without visible errors but the long strings of errors sometimes crashes AE during a render.

I have tried:

Changing the permissions on the scratch disk.

Using a different scratch disk.

Baking all expressions to keyframes

The scratch disk is a seperate, fast ssd card from the application and job folders. 

This has been happening for about a month I update software and OS as they come...

PC specs are:

Ryzen 3900x, 64gb ram, 3 nvme drives (1 for OS+apps, 1 for working files, 1 for cache), twin rtx 2070 supers.

I've updated all chipset, OS, graphics, Software to the latest this morning and no change.

Disable cache usage in the render settings and clean out the cache folder either from the preferences or manually on the physical folder.

I've tried that... results in the same. seems dumb that by some odd quirk I just can't use the cache at all come render time...

I'm having this same issue, I also get a crash notification when closing AE. And regularly get a crash notification, but AE hasn't crashed?

Did you find a fix for the logged diskcache errors?

[GHunsburger]

nope and no response from Adobe.

I've now swapped ssds (channging OS/progs and isolated cache drive) and uninstalled/reinstalled all of my adobe products.

No change to this behaviour.

Hey guys-

I came into work with this same issue. A colleague of mine updated the Avid codec on my system and that seems to have done the trick. Hope this helps somewhat.

Updating Avid codecs for Quicktime worked for me too.
