Hi, I have two 32-bit tiff stacks (generated by ImageJ) and I try to open both to overlay two channels. When opening the second one or trying to open both at the same time (see paths below), I get the following error with the latest stable and daily ChimeraX macOS versions: UCSF ChimeraX version: 1.7.1 (2024-01-23) © 2016-2023 Regents of the University of California.
