What issue are you seeing?

I'm getting a lot of "{"detail":"Bad Request"} errors, almost at every prompt. I've worked on much longer sessions and larger projects before, and this has never happened. The strangest thing about this session is that I changed the working directory once, and switched between gpt-5.5 xhigh, gpt-5.5 medium, and gpt-5.4 medium, although I've done this in other projects without any issues.
