RS-Prerelease build 21343 is out to Dev Channel

In checking on another posters issue with Search I found a different one.

If I open Search it is blank and then closes.

It did this 2 times in a row and then opened fine.

Subsequent times it opened blank, crashed, then opened fine.

There is a Search Application stopped working in Reliability Monitor.

Resolved after a shutdown.

 That last one in your list (time to display list of OSes set to 0) affected some of my multi-boot systems for this as well as the prior two builds.  It affected ALL of my 8 systems with 21343 but only affected a few at random in the prior two.  

I have 2 machines with Dual Boot, I've seen this problem on and off on different builds, but not the 21332 and 21337, now it is back on both machines after W.U. went up to 21343.1000.

In dark mode I see dark text on File Explorer search box, turns white after I click search
