CRITICAL ISSUE : An active PHP session was detected due to Woocommerce plugin

I’m running Woocommerce 4.9.0 and LTL Freight Quotes – YRC Edition Version 2.2.2, and I’m getting three critical errors in site health. They all disappear when I deactivate the LTL Freight Quote plugin. They are:

A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.

The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.
The REST API request failed due to an error.
Error: cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received (http_request_failed)

Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.
The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error: cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received (http_request_failed)

Can you have your developers look into this and see what can be done to resolve these errors?
