By any chance also have and upgraded Alexa Media Player integration?

PSA: Alexa Media Player v4.13.3 breaks all versions of Home Assistant

as FYI…looks like the plan to block AMP in HA has been reverted according to this PR now that AMP v4.13.3 has been pulled @poudenes you asked about the block too so just FYI

[MaxK (Mark)]

2024.5+: Tracking down instability issues caused by integrations

If you find your system unstable because of a misbehaving integration, there are a few methods for identifying and recovering from the problem. It is recommended to use Home Assistant’s built-in debug mode in conjunction with asyncio debug mode.

Using Home Assistant's built-in debug mode in 2024.5.x or later (preferred)

If you are using version 2024.5.x or later, Home Assistant has a built-in debug mode: <a href="https://www.home-assistant.io/docs/configuration/troubleshooting/#han…

[agala68]

Yes, it may be, but I think some days before the core upgrade.
I have Alexa Media Player 4.13.2

[agala68]

Thank you, I will try

[Edwin_D]

If you have that version, that is definitely causing problems.

[agala68]

I have rolled back to 2024.9.3 and “it seems” stable again

[agala68]

So, you suggest me to upgrade it to 4.13.3 and upgrade back core to 2024.10.0?
HACS is not suggesting the AMP upgarde, why?

[Edwin_D]

The AMP version was pulled because of the problems. 2024.10.0 and 2024.10.1 work fine for me, but I do not use AMP.
