Hi @menemem!
Just for testing purposes, can you try to use the Storefront theme?
I’d also recommend that you update your WooCommerce to the latest version, which is 6.0.1 and then disable all of your plugins except for the WooCommerce.
If you get any errors (with everything disabled and using the Storefront theme), can you drop the System report and fatal errors log again?
My very best!
