Can you please confirm that the macro assets themselves still exist in the project and are correct (no errors there)?
Can you please contact me via Discord PM (https://discord.gg/97q2Rjh) or email (support_AT_paradoxnotion.com) so that I can help you fix this more directly? It would also be very helpful if at all possible, if you can send me the project so that I can fix it for you.
