Additional Information

First of all, I'm korean. So log and screenshot text are written in korean.
Sorry if you have any inconvenience to see them.

At "gpedit.msc", navigate to "Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options" and enable "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" will produce same issue I guess.

It seems use SHA1 for check config file integrity but maybe its too old algorithm.
And I checked 7.20 run normally if disable fips policy, too. (with some filters are disabled idk why :))

One more, I saw #1033 issue and I know enable fips policy may seems odd.
But, as AdGuard worked with it at previous version, I think latest version should work, too.
