The debug.log seems to be incomplete since it doesn't log any connection problem (e.g. cannot connect to proxy or to other node). You should check your system log and see message which generated by Tor.
If you can, check if you have any peers - maybe there are no Tor v3 peers for your node, although I would be baffled if that is indeed the case.
debug.log file state peers.dat has 57414 addresses, so IMO it's very unlikely. Although OP can add node which use .onion link from
