After the latest core update 2026.1.1 (I also did an update from 32-bit to 64-bit OS), my HA went bananas and I was not able to access the interface. It was just loading data forever after login. I cleaned caches, tried different browsers, flashed the SD card 3 times, switched to SSD over USB but nothing helped (who would have guessed 
)So I had to go back to 2025.10.2. I have googled quite massively but haven’t found any answers which explain the root cause yet. Does anyone have any idea of what is happening? (I do not rule out the chance that I am the problem though 
)
I’m guessing network issues. Maybe your configuration type was not tested during core updates release configuration?
What do the logs say? [</> formatted please]
What network configuration and IP addresses are you using?
