With 2021a I get this error:
Writing DET for W:\NewRigFiles\LEFTRigDAQ1\2018\July2018\July01_DAQ1_[D]6-27-2018[T]11-17-30%\DET\S1\July01_DAQ1_[D]6-27-2018[T]11-17-32%.mat

The source code (E:\GoogleDrive\programming\MatLabProjects\MultiCatdetect2019\ClassifyMultiCatArray.m) for the parfor-loop that is trying to
execute on the worker could not be found.
Error in MultiCatOnEEGFileNames (line 69)

Caused by:

Error using remoteParallelFunction (line 84)

Undefined function 'ind2rgb8' for input arguments of type 'uint8'.
No problem with 2019b
What changed?
Thanks,

Do you have mapping toolbox in the newer version? Does anything show up if you test with which()?
which ind2rgb8
If you don't have mapping toolbox, you can probably use
im2uint8(ind2rgb(picture,map))
or if you don't have IPT, you can do
uint8(ind2rgb(picture,map)*255)
That's just my guess though. If there are common pitfalls using parpool, I wouldn't know.

You were right DGM. I needed to install the mapping toolbox. Although I did not get the message stating that until I took the code out of a "parfor" loop and put it into a "for" loop. Now that the mapping toolbox is installed I put things back into the parfor loop and all works fine.
many thanks,
Dan
