Getting black screen added to timeline

I am not entirely sure how to explain what is happening, so I have added a video of this weird situation. I have added motion to my talking head video clip to slide to the side when a graphic comes onto the screen. When editing this, there is no space in between files, but the playback will show an all black screen very briefly. It only does this after I have clicked out of Premiere Pro (clicking on a web browser or another application) and back into Premiere, and started the playback. I can replay it again right away after seeing this black screen, and it will NOT be there again (which is in the attached video). It will be there in the final file after exporting.

I am working on macOS Sequoia version 15.5. I am on version 24.3 of Premiere Pro since I am not a fan of the recent updates at all. Any idea on how to fix this? Hopefully not by updating to the horrid newest versions.
