I am experiencing a color shift out of nowhere

Been working on this project in 22. For bug reasons, I ended up opening it in 23 which has been relatively stable to me. When I did a recent export, a client called out that it looked different. It did. My source clips are now all darker for some reason, and the kicker is that 2022 and 2023 are both displaying it this way. I haven't changed color settings in months, I don't know what would have changed. I'm not using any input luts here, it was all manual color, but the actual source clip looks darker which is rippling through. The attached screenshot will show the program monitor from premiere and the resolve program window. Color space is and always has been 709. Footage is fs7 mxf, i don't know exactly what color profile was shot, but it's being interpreted 709 in the interpret window. This is like the end of this project and this came out of nowhere and hit me like a truck. I'm going to put the picture in a reply because the posts keep getting flagged.
