    I started getting this issue after publishing with unity collab. Closing and reopening seems to have resolved it.

    In my case, bug occurred directly after upgrade, no build required, and the setting was for Standalone/PC.

    A restart sorted it, and the bug has not recurred after building for iPhone.
