Error checking in buffer: The buffer you checked in was not checked out

Hi

I have a WordPress multisite, recently which is extremely slow and multiple users reported that JetPack is blocking their login.

The following error keeps coming up in the error logs.
Error checking in buffer: The buffer you checked in was not checked out, referer: https://domain name/wp-cron.php?doing_wp_cron=1645574339.4824481010437011718750

From the dashboard an alert appearrs when navigate to JetPack as “Failed fetching site data from WordPress.com (unknown_token).
”
Can you please assist.
