Notice on core function

I have this weird error (I guess) since this morning in my logs :

[23-Nov-2021 14:46:50 UTC] PHP Notice: Undefined offset: 3322309 in ..../wp-includes/class-wp-query.php on line 3275

Where the 3322309 is increasing for no reason. I see this in my PHP logs, but it's increasing even if my server are down.

This is the code concerned
