No processes found in Assistant


I am using Assistant 20.10.2 and everything has been OK until last week when there was suddenly “No Processes” as shown below.

I have tried to re-connect the assistant to Orchestrator and the problem remains, though I am still able to run all the programs / robots that I have installed previously.

However, after I updated and published a process to Orchestrator and tried to run the new revision from Orchestrator, following error message came:

If I “rollback” to previous revision, it is still working.

Can anyone advise on the above please?

Thank you and look forward to you.
