Using your havc_test version the encodibg works.
The speed in fps is shown after about 3m43s.
But you should see at least the frames colorization on the server side.
If you don't see nothing this imply the client is not properly connected to the server, in the last tversionof DiTServer the client connections are logged.
Moreover my torch package version is different from the one that you are using.
On my PC is installed VapoursynthR74_torch_2026.04.21.7z and in this version is missing the plugins folder. My version is still looking for plugins in "vsfilters", but I don't think that this is the problem because the errors in loading the plugins are reported, but you don't see nothing, very strange
Try to delete the files cache *.pyc in vsdeoldify package, maybe there is some misalignment on complied python code.

I tested your configuration
using this script
But I noted that you was using the local version, not the remote version (encode_mode=0)
Using the local version you need to decrease the max_memory_frames=2
Using the local version with max_memory_frames=10, the client window was plenty of messages like this
Please try using the remote version of HAVC_cmnet2dit()
Thanks,
