hi,

Even i encountered this bug while trying to import JSON data to MySql. I cancelled the import half way through.

Is there a fix for this problem? If yes, kindly share the solution.

Experiencing same bug... 
Windows 11 Pro for Workstations build 22621.1992
MySQL Workbench version 8.0.33 build 2947366 CE (64 bits)
Here is the Action Output I'm getting
17:33:28	DEALLOCATE PREPARE stmt	Error Code: 1243 Unknown prepared statement handler (stmt) given to DEALLOCATE PREPARE	

Also, window that pops up titled "MySQL Workbench Unexpected Error" states "Cannot access a disposed object." Object name: '_ProgressBar'.
