This application has requested the Runtime to terminate it in an unusual way"

Hello.
I use Comodo Firewall version 5.12.256249.2599. I have been using it for many years without problems. Till yesterday.
It shows “This application has requested the Runtime to terminate it in an unusual way” at start Comodo Firewall.
I reinstalled Comodo, reinstalled all Visual C++ Redistributable on my computer (2005, 2008, 2010, 2012, 2013) and additionally installed 2015 and 2017. X86 and X64 version. Nothing has changed.
See the attachments (polish language).

What else can I do?

Sorry for my bad english.

May you please install the latest 10.x version and see if you still have the same problem?

Many people says that the latest versions work slowly. That’s why I preferred to have older version.

The latest version is light as a feather.
I think Comodo 6 was noticeably heavier than 5 due to the extent of the changes, but it’s much more optimized now at version 10.

Hello.
I found a solution. Problem was in the file “cislogs.sdb”. When I deleted this file, Comodo starts normally. When I restored it, Comodo crashed again. This is a firewall logs probably, so I don’t need it.
Thank you all for your help.
