"Application Restart Needed" When Opening File

I've been consistently getting the "A problem caused the application to stop working correctly." on a file that is 617.7 MB. I've restarted my Mac (2021, M1 Max, 32 GB Ram, with macOS 14.4.1 installed) and run ONLY Dimension (Version 3.4.11) and no other apps. I have 227.85GB of 1TB storage free. The dialog box is telling me to gather the log form and attach it via the Report a Bug via Feedback panel...I'm not sure if this is that "panel" but it's not clear where else it is. I've had numerous issues with Dimension and files over the past few years. I've created inerative versions of my files and name them "Opened_XX" with the date so that I know which ones I might be able to use. In the past I found that I was running out of storage and clearing my HD space helped, but right now, I've got a good deal of free space/RAM, so I'm not sure what else to do. 

I did work through uninstalling Dimension via the Creative Cloud Cleaner Tool as I've seen recommended in other forum posts. I have a deadline that I really need to be able to use my file and this is really messing me up!
