Description:
Importing a csv file (from excel) into an already created table.
testing I find I needed to edit a datetime field as it did not import the value.
I cancelled the import. and the error occurred.
Cannot access a disposed object.
Object name: '_ProgressBar'.

There was a corresponding output shown: DEALLOCATE PREPARE stmt  OK
teh table was 
mysql> explain power;
+---------+--------------+------+-----+---------+----------------+
| Field   | Type         | Null | Key | Default | Extra          |
+---------+--------------+------+-----+---------+----------------+
| numb    | int          | NO   | PRI | NULL    | auto_increment |
| dattime | datetime     | YES  |     | NULL    |                |
| power   | decimal(5,2) | YES  |     | NULL    |                |
+---------+--------------+------+-----+---------+----------------+

date to be imported was a dattime and power from the csv (32,506 lines)

20/03/2026 00:03,0
20/03/2026 00:04,0

How to repeat:
create the target table.
import the table using the wizard in workbench,
cancel the task after realising the date is not structured correctly in the csv file.

This issue applies to the legacy MySQL Workbench 8.x implementation that is no longer supported or maintained.
MySQL Workbench 26.7 is a complete rewrite using a new technology stack and does not use the affected legacy implementation.
Therefore, this issue is not applicable to the current MySQL Workbench product and as such is closed.
