Notifications don't work on windows

[try4cou]

Hi,

I'm using Hass.Agent latest version and I can't set up notifications on my computer. I can't even send a test notification on my windows 11 pc. Notifications are allowed in windows settings.

My log contains the following error:

2023-03-10 11:39:39.301 +01:00 [INF] [NOTIFIER] Attempting to show test notification ..
2023-03-10 11:39:39.314 +01:00 [INF] [NOTIFIER] Test notification attempt completed

Please help me to solve this issue.

Your help thanks in advance,

I am running into the same isue. I get the following error on startup:

System.InvalidOperationException: Failed initializing notifications
 ---> System.IO.IOException: Det går inte att skapa en stabil underordnad nyckel till en temporär överordnad nyckel.

When I press the test notification button, I get

2023-05-02 00:53:30.677 -04:00 [INF] [NOTIFIER] Test notification attempt completed

But despite this, no notification ever shows up

Was pretty much getting the same errors as @try4cou the key was (I believe)
[NOTIFIER] Notification failed to show: Settings prevent the notification type from being delivered. (0x803E0114)
followed later by
2023-05-16 15:24:22.172 +01:00 [FTL] [PROGRAM] FirstChanceException: Element not found. (0x80070490)

Turned out I had Windows "Get notifications from apps and other senders" turned-off in "Notifications & actions" oddly although Hass Agent "Show Test Notification" failed to appear the sound could still be heard.

Might be worth checking "Notifications & actions"
