"Unable to move the cache: 0" ERROR with HTML Template

Hello to the community,
I have created a lower third overlay system with casparcg.
I load an animated banner (video file) and then I add text using an HTML lower-third template.
Sometimes, I would say around 5%, the HTML template is not displayed at all and the console gives an error message about the cache :

[2023-05-05 14:04:42.728] [info]    Received message from 10.238.156.27: CG 2-11 ADD 1 lower3rd 1 "{\"f0\":\"John Doe\",\"f1\":\"Piano\",\"f2\":\"Soprano\"}"\r\n
2023-05-05 14:04:42.728 [info] Received message from 1[0505/140442.729:ERROR:cache_util_win.cc(19) Unable to move the cache: 0

23[0505/140442.731:ERROR:shader_disk_cache.cc(622)] Shader Cache Creation failed: -2

The problem seems to appear randomly, I have not found any relation with a given situation.

This is meant to be used in a live TV production so this is very annoying. Any hint about this?

Thanks.

Those are some errors from Chromium that I haven’t seen before.
Does the machine have sufficient free disk space?
I don’t have any more ideas without some googling to see if others have encountered this in other applications

The GPUCache dir is created under caspar root so i’d check permissions etc. My production dir is about 300kb but then I have false in caspar config to avoid updates not appearing in the playout. Been running for a couple of years like this. The GPUCache was much bigger before i disabled the gpu

It looks like the location of that cache is configurable if someone modifies casparcg to support it
