All pages ending with /?order were not found... what should I do?

Question

1C-Bitrix

I need help... although I'm in my account on the site, but when I try to go to a lot of "broken" links on my site that end in /? order, I write "Unfortunately, such a page was not found or simply does not exist." Site - online store.
Naturally, such links were found during the analysis of the site .. there are more than 2 thousand of them ((...
what to do with them? delete or relink?
and do it manually? or is there some better solution?
or can the list of pages be blocked?
