Error: unhandled exception: len(s) == length the length of the HashSet changed while iterating over it [AssertionDefect]

Hi,

I was following the README to play on a server when this happened. I'm unsure if it is worth reporting as it is experimental, but feel free to close it.
Server is a proxmox/lxc container with debian 11. Just followed the instructions line by line strictly except for default port as there is another node running there.

[ahmadina]

same issue, any help?

[jangko]

perhaps you can try --sync-mode:full, the default legacy sync mode is known to have many issues

[tersec]

Legacy sync has been removed: #2237
