When I apply a text wrap but only around an object, the program crashes and closes. The other text wrapping tools work fine.

I noticed a blue cercle on the icon of text wrap around an object (see the screenshot joined). I'm not sure this is normal... maybe it would help you solve the problem...

When I click on this tool, a windows opens (see second screenshot) and then Indesign crashes and closes.

You can note that I am using the latest version of Indesign (16.4).

Thank you very much for your help.
