Prerequisites

• I have carried out troubleshooting steps and I believe I have found a bug.
• I have searched for similar bugs in both open and closed issues and cannot find a duplicate.

Describe the bug

When you upgrade to WooCommerce 6.5 while having an activated WooCommerce Admin plugin with version 3.2.1 or lower, you'll get the error Fatal error: Uncaught Error: Undefined class constant 'PROFILE_DATA_OPTION'

Expected behavior

1. No fatal error.
2. Warning message saying WooCommerce Admin plugin has been deactivated to avoid conflicts with WooCommerce plugin is shown after the upgrade.
3. WooCommerce Admin plugin is automatically deactivated.

Note this is confirmed and considered serious enough for us to pause roll-out of WC 6.5. We're working on a fix and will release 6.5.1 to address it shortly.

I have updated latest version 7.6.0 of WooCommerce. After updating WooCommerce I am getting error saying "Database
Missing base tables: wp_woocommerce_order_itemmeta. Some WooCommerce functionality may not work as expected."

I went to "phpmyadmin" I checked that table but I couldn't opened too. I am getting an error saying that "wp_woocommerce_order_itemmeta" is marked as crashed and last(automatic?) repair failed.

How to fix it?
