Hi, I have been export task form bot agent 21.134 and imported in bot agent 21.121. when run scheduler status always "Queued". I tried to upgrade bot agent to 21.134 scheduler was ran, but very slow. How should I do to fix it? thank you,

I believe there might be version backward compatibility issue as you are trying to import from 21.134 to 21.121, I doubt there may be any package/s specific version which is not compatible or not at all available in the 21.121 but is available in 21.134.
