Ensure you have a stable internet connection to check for software updates, and save a backup copy of your source presentation before attempting to merge or modify large files.
Update Microsoft Office and Test in a New Presentation
Software bugs limiting the Reuse Slides pane are often resolved in newer versions of PowerPoint. Updating Office and testing on a fresh file is the recommended first step.
Microsoft frequently releases patches for user interface glitches and pane limitations. Updating to the latest Office build can clear the slide limit bug in the Reuse Slides panel.
Open PowerPoint, go to 'File' > 'Account' (or 'Office Account'), click on 'Update Options', and select 'Update Now' to install any pending updates.
Restart PowerPoint and create a new blank presentation by pressing Ctrl + N.
Go to the 'Home' tab, click the arrow next to 'New Slide', and select 'Reuse Slides' at the bottom of the menu.
Browse and open your large source presentation in the pane. Scroll down to see if it now successfully loads past slide 100.

Use Copy and Paste as a Manual Workaround
If the Reuse Slides pane continues to fail, you can bypass the panel entirely by opening the source presentation and manually copying the required slides.
Report the Issue to Microsoft Support
If the limitation persists after updating and testing across devices, you should report the specific bug affecting your build to Microsoft.
