The problem appears when starting the application. Easily achieved with the test: AdGuard for Safari - Pause 15sec

_If you want, you can give me the beta version of the application and I will check it for you._
@ameshkov
If you fail to check with this test, since I use a certain sequence. I will gladly help. I'll be your beta tester.
So it looks like a duplicate :p

Please export logs
"Export logs and system info" now includes content blockers info so we'll be able to find out what rule is breaking the content blocker compilation.
Also, a couple more questions (please do export before checking it):
@ameshkov
Same as https://github.com/AdguardTeam/AdGuardForSafari/issues/456
Same steps with EasyList Italy instead of French filter, same result.
So, I can narrow the issue to EasyList Italy: the issue go away desabling EasyList Italy.
Here my log (before desabling and re-enabling EasyList Italy):

Thank you!
Here we have an original compilation error:
[2020-11-28 14:03:20.366] [info] Content-blocker com.adguard.safari.AdGuard.BlockerExtension set result : {"result":"error", "error":{"domain":"WKErrorDomain", "code":2, "descr":"Impossibile completare l'operazione. (WKErrorDomain errore 2.)", "userInfo":"{
NSHelpAnchor = "Rule list compilation failed: Invalid or unsupported regular expression.";
}"}
The error seems to have come back, this time affecting Base filter.
Configuration: macOS 11 Big Sur + AdGuard for Safari

Ask a customer to update to the latest version of the app, as I can see from the logs there is 1.8.6 and the latest realease version is 1.8.9.
latest realease version is 1.8.9.
It's 1.8.10 already :)
