On macOS, Activity Montior can get a sample of what a program is doing - select the program in Activity Montior and, from one of the drop-down menus from the toolbar, select "Sample Process".
Please try that when Wireshark is slowly loading the file, save the sample to a file (using the "Save..." button in the window containing the sample), and then file an issue on the Wireshark issue list about this, and attach the file containing the sample to the issue.
