Submitted: 1 Aug 12:14 Modified: 2 Aug 9:27
Reporter: David Forster Email Updates:
Status: Verified Impact on me:
None 
Category:MySQL Workbench Severity:S2 (Serious)
Version:8.0.21, 8.0.22 OS:Microsoft Windows
Assigned to: CPU Architecture:x86

Description:
When attempting to connect to a database requiring SSL, but SSL set to 'No' in WorkBench, I pressed cancel on the "Opening SQL Editor" and it presented me with the error:

"Cannot access a disposed object
Object name: 'HUDForm'."

How to repeat:
Target DB user set to require SSL.
In WorkBench, set SSL to 'No'.
Attempt to connect to the Database.
Then press 'Cancel'.

Error appears.

Hi all, 

I managed to open MYSQL workbench after downloading the older version 
8.0.20 instead of 8.0.21. 

Comment from my school IT staff:

You can try installing an older workbench. It's a bug in SQL workbench for Windows 10.

After installation of 8.0.21: tying to connect to localhost takes a VERY long time, pressing Cancel returns this error. Is there a solution to this??

In my case, error appears when the connection is configured as: 

    USE SSL: "If available"

Setting this configuration as:

    USE SSL: "No"

Error does not appears.

Yes, a problem. New to Oracle/Mysql.  How in the world do you contact anyone? I know my software has been free but!!  Does anyone post a running update on what is happening in terms of a solution?  Do I delete Mysql, find an older version? Error page shows outstanding for 66 days.

Experienced the same error. The workaround is to install an slightly older version. I used v8.0.19 instead of v8.0.22. Maybe even .21 works for you... didn't try.
You can find older versions at https://downloads.mysql.com/archives/workbench/
