Project opening upside down with additional glitches around applied vfx

version 24.2.0 (build 71)

MacbookPro M2 Max

macOS Sonoma

I have applied masks and rotoscopes to my layers and pre composed them.

On this occasion, when opening the project the enitre video is upside down. I've tried opening other projects and they are all opening upside down.

Additionally the rotocoped layers seem to be the right way up but now acting as a mask.

Please help. Everything was fine last night.
