Facebook and Instagram not logging in. Stating "Your Request Couldn't be Processed"

Steps to reproduce:

Go to facebook or instagram
k. Attempt to login, states that "Your Request Couldn't be Processed".
I attempted to log into Facebook in both compatibility mode, and with various features turned on and off. I also attempted to log into the page with a different user agent, and that did not work.
Further, the auto entry of my username and password also forwarded to the page.

Expected behavior:

Orion, OS version; hardware type:
Version 0.99.121.1-beta (WebKit 614.1.20)
MacBook Pro (macOS Ventura 13.0 build 22A380)

alexjsteffen I am not able to reproduce, logging into Instagram without problems.

You can try Develop -> Empty cache or Resetting Orion.

Hi Vlad,

I noticed that this only occured when I enabled some experimental features for WebKit. It appears to work at present.

Thanks,
