There were some updates to now 1.1.0.0 for AI-Studio. From what I understood also the new GPT-5 was a reason for these updates.
What about checking your issue with the latest AI-Studio ?

Sorry, there was an error in the version number. I use Version 1.1.0.1.

We have indeed from today seen a new issue with function calling and GTP-5.
We are investigating this. We didn't find a solution yet. For function calling, please keep using GTP-4.
