NodeRed gets stuck on Loading Plugins phase.

[krue81]

Problem/Motivation

NodeRed is stuck on the "Loading Plugins" splash screen when using Edge for Windows 10 browser. This behavior started suddenly, no HA or NodeRed updates have been applied lately. And, this issue persists even after rebooting the RPi and a full cleaning of the Edge cache/history/users.

To clarify, I've been using Edge for the past year without any problem when accessing my Hass installation.

All flows work ok.

The strange thing is that if I use Chrome for Windows, NR loads successfully. Also when accessing NR via the Android app, but, I've read of some users with the opposite issue: NR loads ok con Edge and stalls loading plugin when using Chrome or the app.

Expected behavior

NodeRed loading fully, without getting stuck on the loading plugins phase.

Actual behavior

NodeRed keeps getting stuck on the "Loading Plugins" splash screen.

Steps to reproduce

In my case, everytime I try to load NR on Edge for Windows it gets stuck, but, I've read of some users with the opposite issue: NR loads ok con Edge and stalls loading plugin when using Chrome or the app. (https://community.home-assistant.io/t/nodered-stuck-on-loading-plugins/301680)
