PhotoShop v22.4.2 error loading index color images

Hi JJMack, many thanks for taking a look at this.

The output we have that used to load into PS v21.2.9 (but won't now load in v22.4.2) is generated from non-Adobe code.

We can read the file into PS as 8-bit contone and then save it out from V22.4.2 which then loads fine in both PS versions.

The PS->FileInfo>RawData for the two version of the file is here:

This versiom of the file only opens in Phosotshop V20.0.2 but not in V22.4.2 (File info from PS 20.0.2):
