Comment (by s7r):

 Looks like it's more serious.
 So the jammed Tor instance that generated the logs in #21969 never healed
 even after 7 hours of waiting. Was running TBB 7.5 so it was Tor 0.3.2.9.

 Switched to info log level, closed TBB and launched again. Tor launcher
 never fully load, and was just blocked in the loading state with text
 "Establishing a Tor circuit". Captured and attached a screenshot for this.
 I gathered info log for few minutes in this state, and terminated by
 clicking cancel on Tor launcher.

 Then I switched to debug log level and launched again. Tor launcher
 remained blocked at the same loading level as before. I left it in this
 state and gathered debug logs for about 20 minutes, then clicked cancel on
 Tor launcher to close.

 Tried about 5 more times, still the same result. The only thing that fixed
 it was the deletion of the '''state''' file. After I deleted the state
 file, Tor launcher fully loaded in about 3 seconds and browsing went on
 just fine.
