Clip becomes black whenever any graphic is place above it

hi @jamieclarke apologies thought I had provided the necesscary info. TBH in looking over the how do I write a bug report guidelines I'm not sure what info is missing that you need? I'll post in the outlined format for clarity:

Issue - clip becomes black whenever any graphic is put overtop
Steps to reproduce - my clip is on video track 1. Whenever I try to add any graphic overtop it becomes black for exactly the duration of the graphic.
Expected result - the text should appear overtop of the clip, not render the clip on video track 1 completely black 
Actual result - the clip beneath the graphic becomes totally black with only the graphic visible (see screen recording from original post)
Adobe Premiere Pro version - 25.1.0
Operating system - macOS 14.7.3 
Video format - prores422 1920x1080 mov 24fps

To answer your questions:

-deleting the render files in the area has no effect, the issue persists

-the clip is nested. When I take the underlaying clip out of the nest, placing graphics overtop does not make the clip black, seemingly fixing the issue, HOWEVER: I need to nest the clip in order to apply certain effects to it. Why would text render a nested clip totally black and not an unnested clip? This appears to be the bug. Let me know if I need to repost/rephrase my original post to be about this specifically.

Hi @knbstewart -  Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?

It looks like you are trying to add the text over an area that has been rendered.  Can you try selecting the menu bar under Sequence and click "Delete Render Files".   Are you adding the text over a nest?
Sorry for the frustration.
