I have had this for a while now, whilst I have constantly updated to the most recent release (2024.11.1 core, 2024.11.2 supervisor, OS 13.2, frontend 20231106.1)
When I go to a helper, I can click on it and it opens the page with the current state. If I then select the cog to enter the settings, I get a blank pop-up, only displaying the name of the helper in bold, with an β<β in front of it to return to the overview/current state of this helper. I do therefor not have a chance to change the name, or add items to an input_select list. It works normal for entities.
As nobody has been complaining loudly about this (and I found nothing in google or chatgpt), I presume it is a local issue.
I run Home Assistant in a VirtualBox on an Ubuntu NUC, over an SSL connection.
