Status:	Can't repeat	Impact on me:	None
Category:	MySQL Workbench: SQL Editor	Severity:	S1 (Critical)
Version:	8.0.21	OS:	Any (Build 16448441 CE)
Assigned to:		CPU Architecture:	x86 (INTEL Core I% 6400T 2.2GHZ)

Description:

Description:
After download and installation of the newest version of MySQL Workbench without any problems, I started MySQL Workbench for the first time. After clicking the local connection button, it clocks  for many minutes with no results. I then clicked the Cancel button of the Open SQL Editor screen and this message appeared: "Cannot Access a Disposed Object. Object Name : 'HUDForm'.".

I attempted restarting the computer and verifying the MySQL service was running, which it was and still got the same results.

I had a previous version of MySQL Workbench installed, But this old installation was completely removed before the new installation of MySQL was reinstalled

How to repeat:
1. Launch MYSQL Workbench
2. Click on MySQL Connections -> Local

My experience is the same. I uninstalled a prior version of all MySQL programs including WorkBench and installed the latest version of MySQL Workbench but it won't open.

Hello MARK COMPORT,

Thank you for the bug report.
I tried to reproduce your issue on windows 10 with workbench 8.0.21 but I am not seeing any issues at my end. To investigate further this issue at our end, may I kindly request you to launch workbench under debug mode (-log-level=debug3) and provide unaltered workbench log file(more details about log are explained here - https://dev.mysql.com/doc/workbench/en/workbench-reporting-bugs.html). Thank you.

Regards
Ashwini Patil

I have added 2 log files when this happens. Please review.

When you say:
For example:

# Microsoft Windows
shell> cd "C:\Program Files (x86)\MySQL\MySQL Workbench CE 8.0.21\"
shell> MySQLWorkbench.exe -log-level=debug3

Where are you when you are editing this? In the command shell of Microsoft or in MySQL shell?

when I I enter this in MySQL shell it says invalid. when I try to CD to the location in Microsoft this is what I get:
C:\Program Files (x86)\MySQL>dir
 Volume in drive C is Windows
 Volume Serial Number is DA44-A86E

I had problems connecting local server 5.7, configuring server would hang.
Uninstalled server and manually removed folders: 
C:\Program Files\MySQL\MySQL Server X
C:\ProgramData\MySQL\MySQL Server X

Installed server 8.0.21
Click on 'Local instance MySQL', hangs.
Click Cancel, and the described error appears.

My fix: right-click on 'Local instance MySQL' and select "Start command link client"...it asks for pswd, enter pswd...ok.
Now each time I click on 'Local instance MySQL' the normal password popup appears and works as expected.

I attempted the Fix as you suggested and it is still doing the same thing, even after I put in the password. Any other suggestions? It seems there are bugs in this workbench working with Win10.
