Also deletion of the device or entities is not possible/successful, the error occurs again and again.

I am having the same issue, but on an iPhone… HA core: 2024.6.4, supervisor: 2024.0.6.0, OS 12.4, front end: 202406.10.1 - Running on a VM (Proxmox)

I finally managed to solve the problem for myself: I uninstalled the mobile app on my smartphone, restarted HA and then deleted everything related to the "Mobile App" integration (entities, integration entries, etc.).
Then restarted HA again and started from the beginning. Now I only have one device and all entities are correct again. And no more errors in the logs :-)

[jgloor]

I tried to delete everything.. it changes the integration entries to "Not Loaded." I have 1 Entity left - it's marked as disabled and will not let me delete it or enable it.

Note: I was able to re-add my phone, and it works now... but still unable to delete the 70 entities from before.
