can’t update products if plugin is enabled

Hi! I bought some weeks ago Tags Group plugin.

I have an issue when your plugin is enabled.

If I click “update” in any woocommerce product, appear a console error and don’t save the changes:

Uncaught TypeError: Cannot read properties of undefined (reading ‘length’)
at HTMLInputElement.<anonymous> (post.php?post=119833&action=edit:11494:26)
at HTMLDivElement.dispatch (jquery.min.js:2:43064)
at v.handle (jquery.min.js:2:41048)

If I disable the plugin, I can save the product without issues.

Can you fix it?

Thanks
