for details.
After reading through #22576, I think they are not related. I don't use
squid HTTP proxy.
I added more tests above, and pretty sure it's not obfs4proxy problem.

It's probably the new '''guard''' feature drawn into Tor-0.3. There exists
two clues:
1. Based on all comments so far, I narrowed down the issue to Tor-0.3
binary. I also tried to replace Tor binary in 7.0.1 with 6.5.2. But it
reports error:
{{{
Launching './Browser/start-tor-browser --detach --debug --log'...

}}}
2. If we compare the log difference between Tor-0.2 and Tor-0.3 above, the
later exclusively contains a special line:
{{{
Starting with guard context "bridges"
}}}
3. Although no circuits built with bridge and obfs4proxy, Tor-0.3 onward
works greatly with Socks5Proxy option support since that proxy bypasses
censorship successively.
