Is Junie just plain broken?

Literally every time i ask for it to do something it will do a great job at making a plan but then just won't be able to execute it with endless “Failed to submit tasks”. Once this happens , i can sometimes get past it by typing something like “you crashed, please continue with the plan” - but you have to do this again and again. Often times it will also just come up with : “Unknown exception occurred during the agent execution”.

It's basically unusable, is there anything i can do?
