Gui Crash beyond repair

[Macphesto]

Hi! I was using Tribler and THIS happened! 😢

Failed to execute 'querySelectorAll' on 'Document': The provided selector is empty.
SyntaxError: Failed to execute 'querySelectorAll' on 'Document': The provided selector is empty.

Thanks for the report! The fix for this issue is not obvious: we need more information. Could you tell us what web browser and Tribler version you are using?

using Duck Duck browser and latest Tribler 8.07

Looking at our compiled index.js, we only have three instances of document.querySelectorAll, two of which are unique:

1. document.querySelectorAll('link[rel="modulepreload"]')
2. document.querySelectorAll("[data-radix-focus-guard]") (appears twice)

These both seem to be buried in our dependencies and I expected to find other people with similiar issues. However, I'm not finding anyone with a similar issue in my Google searches.

I just noticed that the line number 17336 is way bigger than the 339 lines of our source code. This error is actually happening within the DuckDuck browser.

elementSelector is calling querySingleReplySelector here: https://github.com/duckduckgo/autoconsent/blob/94fa72e2bcbd985a34dbfcc4001807fe4fb8d68b/lib/dom-actions.ts#L150

elementVisible is calling elementSelector here: https://github.com/duckduckgo/autoconsent/blob/94fa72e2bcbd985a34dbfcc4001807fe4fb8d68b/lib/dom-actions.ts#L29C27-L29C43

filterListFallback is calling elementVisible here: https://github.com/duckduckgo/autoconsent/blob/94fa72e2bcbd985a34dbfcc4001807fe4fb8d68b/lib/web.ts#L556

This suggests that the passed selectors (getFilterlistSelectors(cosmeticStyles)) are empty.

Currently, this seems like a DuckDuck browser "autoconsent" bug.

I tried to massage our web page to not trigger this bug in the DuckDuck browser. However, the browser is just too broken.

@Macphesto if possible, I'd try to disable the autoconsent feature. From our side, we can't fix this.

Thank you for trying 🙏
