Unable to open "Trainers" Tab without crashing

[ZenominFolgard]

Title is main explanation, every other tab can be opened without difficulty, but when I attempt to open trainer tab, I get the below message and it crashes:

The program must now close.

Please provide assistance. Thank you

Please provide more information on what game you are trying to edit. I assume this is a fresh dump of the game, and not a ROM hack already edited by others? #565

[ZenominFolgard]

My apologies, I have zero experience in this space. I am working on a base ROM of Omega Ruby, and have edited the team of one trainer so far and evolution methods of a number of Pokémon, as well as the prices of a few items. I did all this before ever closing the program, and upon loading it up the second time, have encountered the above issue. Please let me know if I can provide more details.
