I struggled a wile !!
So I thought I could share the solution 
If one gets this kind of error on a debian 11 fresh install... the distro package at this date is
$ rclone version
rclone v1.53.3-DEV
- os/arch: linux/amd64
- go version: go1.15.9
just
apt remove --purge rclone
and get the .deb from Rclone downloads
I find it sad that such a good tool as rclone has a broken version in there... Rclone deserves better treat 
hav a nice day
