The exact same thing happens to me every single time I re-open my scene. Blurry camera, my saved views are suddenly very dark, lots of flicker from the Lumen engine, basically have to start setting up everything again.
I have not found a fix. At some point TM crashed, and that was the only time when it opened the file and everything looked correctly as it had been saved before the crash. I’m on a Mac (Sonoma, Intel iMac), and unfortunately crashing TM manually does not solve the problem.
