Problems with transitioning to 2019b compiler

I have code that I have successfully compiled and run using mcc with 2018a. With no change to the code, if I try to compile it using 2019b, I receive the following error when running the compiled code:

Cannot find nonembedded CTF archive

If I change my MCR_CACHE_ROOT to . as was suggested in this answer I get the following error dialog.

If I go back and recompile using 2018a, everything works as intended.

Any help would be appreciated. Thank you.

Adding the -C flag as mentioned in this bug report appears to fix the problem. Though it does require me to distribute a second file.

And it does bring up the question of what changed between versions to cause the issue.

If a more complete solution is available, it would be appreciated. Thank you.
