Hi @BrekLin
May I ask what is your macOS and your Office version?
Does it show any error when the apps crashed? If yes, can your please provide it.
Here are some basic troubleshooting steps that might help:You can try reinstalling the Office suite via Update history for Office for Mac - Office release notes | Microsoft Learn.
You can download the latest version or if you do not meet this behavior in previous version, you can consider downloading older version such as 16.104.x.
Try Start up your Mac in safe mode - Apple Support (SG).
