biblioshiny Error After Setting Gemini API Key in Version 5.1.1

[fuck007996]

In version 5.1.1, after entering the Gemini API Key and clicking "Set API Key," the program exits after a few seconds, and RStudio displays the following:

> biblioshiny()

I have tried the following methods, but the problem is still not resolved. #534 (comment)

API：I created the API key in Google AI Studio, clicked "Copy API key," and pasted it into the 'Biblio AI' API Key input field.
