I've never experienced this in my testing.
I've been on the beta channel with 2 machines for quite some time.
Today I find on one of my machines that ASB begins its launch only to close just prier to launching. The second machine ASB is launching.
Decided to try a reinstall; I used the Browser uninstall tool and reinstalled ASB (v.88.0.7791.97) but still doesn't want to launch,
Don't know whats up as it was fine this morning and I have not manually changed anything.
Edit: I'm pretty sure the Browser just updated to v.88 on both machines
