• After a while, when trying to convert, i receive an error message Error: Connection errored out when converting Wav files.
• The Wav files is 51 sec long.
• used all the alghorithms pm harvest crepe rmvpe with same result

This is my config
cpu 9800x3d
gpu 5090
64gb Ram 6000mhz
RVC latest

Start with infer-web.py and the reported PyTorch CUDA warning; reproduce conversion using the 51-second WAV on the RTX 5090 and inspect the conversion error path. Done means conversion completes reliably or the issue records a confirmed compatibility limitation and its required resolution.
