safe mod not always start https://yadi.sk/i/8yG56oKfoB8vGw
and close all my tabs!

I am very much concerned about this situation, because cent browser allows you to have many tabs. A similar browser with the ability to tabs like Firefox does not have.
And you do not publish the source code, at least tabs, so that I can build a browser based on vivaldi or pure Chromium + tabs patch.
Well, or you yourself build vivaldi + tabs patch or pure chromium + tabs patch

It is used just for testing.

Then you can try disabling hardware acceleration (in chrome://settings/system) and disabling all extensions temporarily.
