I didnt actually have any other sandboxed apps to test, so I just downloaded and ran "fatFileFinder" from here `https://github.com/Ravbug/FatFileFinderCPP/releases/tag/2.2` which appears to be sandboxed - it launches fine from...

Yeah, Handbrake fails in an identical fashion. My permissions in `ls -al` in that directory look identical to yours too. I tried creating a brand new non-remapped directory inside `System/Volumes/Data/`...

I was actually able to get the file to open by replacing the malformed part in a hex editor... LAS X does not seem to care about the error, though.

Software version is LAS X 3.7.4.23463. The file was saved using the auto save functionality in LAS X, then renamed within LAS X. otherwise it was not modified.

Yes. In the example they are named series_0.tif and series_1.tif

Same issue here. Version 1.0, GUI, on a Mac. Using FCS files from a BD Accuri C6. Can provide files if you like.

Glad to hear it. I am no longer working on this particular project, but I was able to complete it by changing the autosave format to TIF for the duration....
