Other info:

I run rclone inside entrypoint of a Docker Container, which is launched from WSL2 Debian distro installed in Windows 11.

part of my docker-compose.yml is:

  comfyui:
    image: comfyui:latest
    container_name: comfyui

I fixed the issue by installing fuse during build stage:

RUN --mount=type=cache,target=/var/cache/apt,sharing=locked \
    --mount=type=cache,target=/var/lib/apt,sharing=locked \
    apt-get update && \
    apt-get install -y rclone fuse libfuse2

welcome to the forum,

that is years old, custom compiled, dev version of rclone from an out of date debian repository.
