ERROR 404, PAGE NOT FOUND when clicking on a product or product

Since the last update, our store (staging: https://96a8b71b.cfolks.pl/) has been displaying the message "ERROR 404, PAGE NOT FOUND" intermittently when clicking on a product or product category. We have enabled debug mode, and the following error is displayed:

Deprecated: strstr(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/allegoryk/domains/96a8b71b.cfolks.pl/public_html/wp-content/plugins/woocommerce/includes/wc-page-functions.php on line 139.

However, the fatal-errors.log file does not show any additional errors.

The mentioned situation occurs once every few hours, and then the store starts functioning normally again.
