Latest Chrome Dev version crashed on macOS Catalina DP 5

Hi.

I'm using Chrome from developer channel for a long time on my macOS.
Since August 14th, 2019, after an auto upgrade of the Chrome, it cannot be launched again. When starts, it shows a empty window with only 3 common color dots at the top left corner and then halt.

Tried rebooting and reinstalling, the problem cannot be fixed.

Currently, I turned it back to the stable channel, which works well.

Sorry that I cannot provide the version number of the affected version, which I cannot get without start it.

Update: In DP6 (19A536g), Chrome Dev version is working well now.
