Thank you for your report.

Can you please tell which Edge version you're using? The "traditional" or the Chromium-based one?
Also, can you please tell whether this appears with all backend users or non-priviledged users only?

It concerns "traditional" Edge. Here I have got Microsoft Edge 44.18362.449.0
I did not check with Chromium-based so far.

It concerns all users. Admins included.
Other new TYPO3 Versions like 9.5.20 oder 7.6.46 (ELTS) work fine.

Tried it myself with Microsoft Edge 44.17763.1.0 and couldn't verify. It all works fine. I only found another issue: https://forge.typo3.org/issues/92001

I tried in Mircosoft Edge 44.19041.1.0 and can confirm that the Page tree is not loading.

Also there is an error in the console:
0: Unable to get property 'define' of undefined or null reference in ImmediateActionElement.js (12,667)

Please see screenshot attached.

In 10.4.5 everthing is working OK.

I think the error you mention (see https://forge.typo3.org/issues/92001) might cause for some people to not show the page tree

Do you have the possibility to check current master branch of TYPO3?

This seems to be caused by #92001. Can you check if the patch for that issue is working for you.

Yes, the patch is working for me. The JS error is gone and the page tree is loading again in Edge. Thanks!
