Tasmota devices disappeared after update to core-2021.2.3

Good evening,
after the latest update to core-2021.2.3, all my ESP8266 based Tasmota devices have disappeared as Entities.
In order to make them reappear, I had to delete them both from Hassio, from the Tasmota integration, and also as devices with TasmoAdmin.
I use an RP4 with 4GB of Ram and the Hassio version.
What could have happened?
I tried, before deleting the devices, also to restart everything, but nothing happened.

Thank you
Giuseppe
