Iammeter integration failure with HA core upgrade from 2023.4.6

I am fairly new to HA – only 6 mos. Today I selected to upgrade my HA core from 2023.4.6 to 2023.5.4. It is running on a rasberry pi. Upgrade took 10-15 minutes. After completion I had lost all my connections to the six iammeters I have installed. These meters failed to load.
I chose to go back and restore my older version and after another 15-20 minutes things were working again.
In addition, for two days now I have a warning “Unsupported System – AppArmor Issues.” I am not sure how to respond to that.
In the last two days I have added 6 or more Tasmota Sonoff S31 plugs and I have added ESPHome with an ESP8266 chip used as a voltmeter. I cannot trace any of these additions to my new problems but I have not been very observant, either.

You can try upgrading to a version after 2024.1.0
