Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This solution fixed my issue. I hope it can help others too. Go to your secure folder, settings, then apps. Uninstall all Microsoft Apps in your secure folder, and this should solve the issue. I can now launch M365 and all of its apps as I normally do. Seems like the dual instance of M365 in my secure folder was causing some sort of conflict. Good luck.
