If you refer to this answer, I think it will probably be resolved.
Pull request #864 proposes a solution by modifying the prompt(in browser_use tool) and token max limits, but that didn't work for me. I had to roll back to a specific version, as the link says.
It seems that this issue occurs especially in Gemini.

For reference, I rolled back to

I had the same issue in a similar environment as you and the rollback fixed it.
