Got it fixed yesterday. No idea what was corrupted or how it got that way... sharing in case anyone may have the problem in the future.
Flushed/cleared these:
Clear browsing history
Clear download history
Empty the cache
Clear saved passwords
Clear saved Autofill form data
Clear data from hosted apps
Then uninstalled Chrome, rebooted, reinstalled chrome and let it auto sync with my profile. That cleaned it up and it has now been running now with no hangs on both the laptop and desktop.
Tried clearing just the stuff above, no fix. Removed/reinstalled, no fix. Doing the two together with a reboot appears to have worked.
