Thanks @agitate I found the reverting instructions on GitHub the simplest for now
Till a patch comes out, you can downgrade woocommerce back to v6.8.2.
Steps to downgrade would be:
Backup the whole site.
Download woocommerce plugin zip (6.8.2) from here
https://developer.woocommerce.com/releases/
Go to Plugins > Add New and upload the zip file that was downloaded in step 2 and Install it.`
Check the instructions along the way as it will detect the new version and check you want to revert.
Trying to find a developer who may be able to do something but as it stands we can’t seem to use product add-ons with Elementor.
