ESPHome - Esp8266 problem with updates

Hi, everyone
I have had a problem with updating esp8266 (esp01-s) for a month now. I receive information.

“ERROR Error reading file /data/storage/esp-piwnica.yaml.json: ‘utf-8’ codec can’t decode byte 0xb0 in position 104: invalid start byte”

Unfortunately I can’t program any other new esp either. I have information.

Library Manager: Installing esphome/AsyncTCP-esphome @ 2.1.3
INFO Installing esphome/AsyncTCP-esphome @ 2.1.3

Maybe someone had a similar problem

Had something like this when having degree symbol in wrong coding.
Suggest to publish configuration file to have more specific ideas.
As well try to open file in Notepad++ f.e. and save it in utf8 coding.
