Comment (by asn):

 Hmm the interesting log message here seems to be:
 {{{
   newcirc = circuit_launch_by_extend_info(CIRCUIT_PURPOSE_S_CONNECT_REND,
                             oldstate->chosen_exit, flags);

   if (!newcirc) {
     log_warn(LD_REND,"Couldn't relaunch rendezvous circuit to '%s'.",
              safe_str(extend_info_describe(oldstate->chosen_exit)));
     return;
   }
 }}}

 Unfortunately without info or debug logs it's not possible to get deeper
 here :/

 If this is something you can reproduce, can you please enable info or
 debug logs?

 You might also want to try a more recent Tor version.

 This might be related to #30200, or maybe not.
