Additional information and/or screenshots

The message says that there is a problem with my hosts, but in reality there is no error.
It is an error in your application’s interpretation of the content.

Here is the content of my hosts file.

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost

It is obvious that files without content but only comments will be considered problematic.
Because after I tried adding a line of content, it was able to run properly.

Could #6114 be the same issue?

@bestpika, hello and thanks for the report. We've pushed the edge release that should fix this issue, could you please try it and tell if AdGuard Home starts properly?

[bestpika]

@EugeneOne1 I have updated to v0.108.0-a.663+2b901931 and it seems to start up normally when tested.

[EugeneOne1]

@bestpika, great to hear. We'll close the issue for now, but you're welcome to reopen it if the issue persists.
