Temporary Solution
At the time of publishing this post, WooCommerce hasn’t yet provided an update on the situation.
For now, the best solution is to roll-back/downgrade your WooCommerce plugin to version 4.3.3.
You can download WooCommerce version 4.3.3 here from the official WordPress plugin repository. Browse through the available WooCommerce versions if you’re looking to downgrade to a version below 4.3.3

It seems like for now the best solution is to go back to the previous version. Thanks for this.
It looks like the last update from woocommerce is not compatible with older php versions. Update your server to the last PHP version
It’s not a PHP software issue, rollback is required. V4.3.3 worked for me.
