Cookie consent pop-up doesn´t show up , page inaccessible

[Dragons1]

Description of the issue:
Page https://www.dance-shop.cz/ loads, the cookie consent pop-up appears very briefly, but disappears and the webpage is inaccessible. Pop-ups are enabled in Brave.
The same page loaded in Firefox - the pop-up shows and after choosing a consent option the page is normally accessible.

I had the same issue with some other pages previously too in Brave, but cannot remember which ones now…

How can this issue be reproduced?

1. Open Brave browser
2. Go to https://www.dance-shop.cz/
3. See that the cookie consent pop-up only shows for a second or less (in the middle of the screen) but disappears again. Page is inaccessible because it requires a cookie consent, but since no pop-up is visible, no consent can be given.
4. See that Pop-ups are allowed in Brave and cookies are also allowed. It also shows cookies from the page.

I tried deleting cache/cookies and starting Brave again, the result was the same.

Expected result:
After loading the page the cookie consent pop-up stays visible, so I can click on either option and afterwards use the webpage.

Brave Version( check About Brave):
Version 1.59.117 Chromium: 118.0.5993.70 (Official Build) (64-bit)

Additional Information:
I´m using Windows 10 Home, version 22H2

Hello @Dragons1 , I had the same issue on another website so if you still have the problem what helped me was to disable the Shields and than activate it again after confirming cookies popup.
