Create a slide show, for example based on template "Candy".
menu View > Master Handout.
Select a thumbnail placeholder.
menu Format > Object and Shape > Position and Size.
Change the size to 80mm width and 45mm height to get a 16:9 thumbnail.
OK. => Crash.

I see the error in debug build of current master

Just for the record, on pc Debian x86-64 with master sources updated today + gen rendering, I don't reproduce this.

After having chosen "Candy" template then View/Master handout, I got:
- 2 placeholders at top ("Header Area" at top left, "Date Area" at top right)- 2 - 2 placeholders at bottom ("Footer Area" at bottom left, "Page Number Area" at bottom right)
- 6 grey/disabled placeholders at center that I can't select : 3 at left, 3 at right

I tried Position/Size with values on "Header Area" and "Footer Area", no assertion.

Perhaps Windows only?

I'm surprised you can't select the placeholder. If you use the mouse, the pointer should change to a cross, when you hover the gray dashes line. A click then will select the placeholder. Or without mouse you can press the tab key several times. That will select the placeholders one after the other.

You cannot select a thumbnail placeholder by clicking into the empty rectangle area. You have to click on the dashed line at the edges of the rectangle.

Thank you Regina for the tip!
I could reproduce the assertion
