Why did 1Password (Windows) stop starting?

Question

Windows

Hello. I use 1Password for Windows. The program is scorched, but there have never been problems. Suddenly one day it just stopped working. Deleted, cleaned the PC using AVG and AusLogics, downloaded the native trial from the site, set = does not start. For the first time in my life, I am faced with the fact that the program simply does not start.
There were no changes in the configuration, only ESET Smart Securitty was installed, but 1Password already worked with it.
Asked a question to their support service - silence.
How to be?
Thanks to all
