Hello @liminspace, I take it you checked the box to remember your password and trimmed the auto-login detail out of your log snippet?
Your log has src/public/tier1/utlmemory.h (176) : Assertion Failed: 0 which is a decent hint that you've encountered the issue being tracked at #7813. Closing as a duplicate.

Steam crashes after start. Before update 8 Jun it worked very well.
If I run
steam --reset, it works. But when I close Steam and run it again it crashes again.
