Plugin Conflict with Product AddOns from Plugin Republic

I received a notification that a critical error had occurred and it was a conflict between your plugin and Product AddOns from Plugin Republic. I’ll also send this message to him, as I don’t know who needs to know. For now, I have disabled the Sequential Ordering plugin.

When seeking help with this issue, you may be asked for some of the following information:

WordPress version 6.1.1

Active theme: Avada (version 7.8.2)

Current plugin: Sequential Order Numbers for WooCommerce (version 1.4.9)

PHP version 7.4.32
