Table Data Export Wizard fails after upgrades

[Michael Homa]

The Table Data Export Wizard fails with the following log errors:

Traceback (most recent call last):
File "/Applications/MySQLWorkbench.app/Contents/Resources/libraries/workbench/wizard_progress_page_widget.py", line 197, in thread_work

I believe these errors were the result of table data that included single quotes in text columns and vulgar fractions like ½. These fractions display correctly in Workbench, and cause no problems in queries or views, and I can create dump files without issue.
I recently upgraded MySQL and Workbench to 8.0.28. During that upgrade I lost the schema involved and had to restore it from a dump file I had previously created with Workbench 8.0.22 and MySQL Community Edition 8.0.23.
Prior to the MySQL upgrade I had converted my iMac to macOS Monterey. After the macOS upgrade, MySQL server and Workbench restarted and operated without issue, but I did not use the Table Data Export Wizard until after I upgraded MySQL and Workbench.
I am using an iMac 27”, 2017, macOS Monterey 12.2.1, 3.8 GHz Quad-Core Intel i5.

I can successfully export table data without using the wizard, by simply executing a query to output all records and then use the export recordset button on the table result panel. The exported csv file includes the problematic vulgar fraction (common fraction).
I have tested the Table Data Export Wizard using a simple table without any "special" characters, and the wizard worked OK.
I have not knowingly changed character sets (and wouldn't know how to do it if I tried). I'm new to MySQL so any advice would be appreciated.
