Something went wrong on flashing thinking experimental?

I use gemini flash thinking experimental, and for the past few days any time I enter a prompt, it stops after a few seconds and says, "something went wrong. Please try again". The chat gets deleted.

I've tried using a different Google account, but it doesn't help. I also tried on mobile, same thing. Someone had mentioned putting a last name on your account. That didn't help either.

Anyone else getting these issues? Could it be a subtle form of rate limiting? I'm on the free tier.
