I have problem with Workbench for about 4 months now. Even Workbench updates did not help. When I connect to any server (have many of them. Clustered and nonclustered) I got delay on first query. It takes like 1-2 minutes to execute. Execution time is something like 0,016s or so. But even SELECT 1 takes that long to execute. It does not matter if it is by SSH or just casual connect. Happens even on my local server on my machine. I start query see blue wheel rolling. If I click somewhere it stops to respond. After 2 minutes it unfreezes. 
Second queries and rest are okey taking notime. if i open another connection to another server similiar problem. If I close connection and connect again same problem.

How to repeat:
On my computer it is just to connect to server via MySQL connections and start whatever query. Also happens to one of my colleagues. Does not matter if I am at home on VPN or at work on local network.

I forgot to add that workbench was working fine first 1-2 months I had it(july 2020). Then it changed suddenly and this started to happen. I have Windows 10.

Hi Ashwini,

thanks for answer. Link you send me did help. I still have about 10-20 seconds of delay after deleting output history but workbench does not freeze so its acceptable.
