How can I prevent the new indexing bug from creating useless pages on Google?

The problem is still not solved knowing that it is more than 2 weeks old for the number 1 host of ecommerce site it becomes shameful. Each day more is less credibility for all your users. Moreover, even today I still have the Wpm and Web pixel Manager pages that appear but I also have a Chinese URL that was not created by me, which has just been detected. So I’m going to ask users if this is related to the same problem as WPM and if they too have detected this because shopify doesn’t seem to want to help us this PROBLEM, or doesn’t communicate enough which makes everything unclear and very unpleasant.
