What's Wrong?

Others have reported this similar issue, however HOW mine occurred is what is of interest. Claude CLI is using appium to test a mobile app in Android Emulator. While trying to troubleshoot an issue Claude took its own screen shot of the app:

Bash(adb -s emulator-5554 shell screencap -p > /c/Users/smith/dev/github/project/emulator_screen.png
       2>&1)

Then it tried to read the image and that's when the error occurred:

● Read(emulator_screen.png)
  ⎿  Read image (1.5MB)
  ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"Could not process
    image"},"request_id":"req_011CVT8Hms2jsAt6mposaatc"}

And now it gives the same error for everything I type into the console:

> what have you found?
  ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"Could not process
    image"},"request_id":"req_011CVTAu66brM5NLB1oYCnet"}

> are you getting that api error?
  ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"Could not process
    image"},"request_id":"req_011CVTAxvQJh3azfXN82dMKd"}

> issue?
  ⎿ API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"Could not process
    image"},"request_id":"req_011CVTB36Nwfy2GTo45yFcjB"}

This forces me to start a new Claude CLI session because this one just hung repeating the same error on anything I type.

What Should Happen?

It should read the image file it took...and not hang.
