Invalid User ID: 0 on Checkout page

Please help me with the following error on our website.

All of a sudden we’re facing this, “INVALID USER ID: 0” on the checkout page for all payment gateways.

Guest checkout is working fine.

I have been in touch with Hosting support and they couldn’t fix it either.

At first, we thought it was a cache issue but we are not sure.

WPMU DEV & Cloudways support tried everything but couldn’t fix it.
