This page can't be found error

Description of the issue:
Hi, when I visit a famous German second hand car website (mobile.de), the website works as it should be until I click on a car insert, so I can do everything on the website, logging in, searching with filters etc. but as soon as I click on a insert, it opens the link on a new tab and I get the error that the page can’t be found. The links are actually working good on other browsers such as Chrome and Edge. Here are some screenshots:

Exact URL of the website in question:
https://mobile.de (the main page which works for me)
https://suchen.mobile.de/fahrzeuge/details.html?id=382485010&dam=0&isSearchRequest=true&ms=3500%3B122%3B%3B&ref=srp&refId=0e94c4c4-b91a-11c9-3067-3cb38a006990&sb=rel&searchId=0e94c4c4-b91a-11c9-3067-3cb38a006990&vc=Car (a link to a insert that brave can’t find the page)
Did the issue present with default Shields settings? (yes/no)
Yes

Does the site function as expected when Shields are turned off?
No
Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
No
Does the site work as expected when using Chrome?
Yes
Brave version (check About Brave):
v1.61.116

Visited the link here, is it still broken? does it work in private window mode?

I was able to replicate a few times, and this was the temporary workaround I figured out (until someone from Brave can fix). There must be something stored in the cookie from mobile.de after you accept their cookie policy that is required for suchen.mobile.de to work fully. There were a couple times where I could visit the mobile.de off the bat, run a blank search, click a few links, but it would start failing after a few mins.

The following is a workaround

1. Clear your cookies
2. Go to mobile.de
3. Turn off Brave shield
4. Accept/Deny their cookie notice (I can’t read German but left option is the opt-out page)
5. Turn on Brave shield
6. Use site to heart’s content
