HPOS fatal error | WordPress.org

Hi,

I get a fatal error on my website when I visit the “Orders” menu in Woocommerce with HPOS enabled and I can’t figure out why this happens.

The posts and orders tables are in sync and no plugins are flagged as incompatible. It has worked before but now this happens every time and the only solution (that I found) is to disable HPOS again while in recovery mode.

I did switch my payment gateway recently but the problem also happened before with the previous gateway. Both should be compatible with HPOS according to the developers. I also get the error when no payment gateway at all is enabled.

Steps to reproduce:

• Enable HPOS in Woocommerce Advanced Settings.
• Click the “Orders” menu in Woocommerce

Below is the fatal error log entry

Can anyone help me pinpoint what is happening? Thank You
