Hello, try to disable your wow addons. Can you share your log file please ( https://wrobot.eu/forums/topic/1779-how-to-post-your-log-file-with-your-topic/ ).
I think than your problem is caused by "Avoid it" plugin https://wrobot.eu/forums/topic/6584-blacklisting-vendors-prior-to-approaching/?tab=comments#comment-29998
Hello, last log before stuck is: "[FlightMaster] Try to take taxi at Древний тучекрыл" (and last combat is with an NPC) Are you sure about player? What is "FixCombat"? Are you sure that problem was caused by WRobot and not profile/fightclass/plugin? You get this problem frequently?
The problem is necessarily on your side. Some software blocks keyboard access, use option "Use lua to move" resolve this problem, if you have big latency ingame, in this case putting a "min / max latency" higher can resolve the problem. Some wow addons and wrobot plugins / fightcalsses can also cause problems.
