Can't upgrade to 0.66.1 from 0.66

Hi,

I am not able to upgrade. After hitting upgrade button I loose connection after short time (normal) but connection isn’t restored. I need to reboot. After reboot I am still on 0.66
When I do ‘hassio ha logs’ via SSH when web page connection is lost, I get this error:

Error decoding json invalid character ‘F’ looking for beginning of value: Failed to import the site module
Traceback (most recent call last):

UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xf9 in position 7: invalid start byte

Anyone can help ?
