Hello, I have already resolved this issue. Since I do not know English, the following content is all machine-translated.
Firstly, you should check if your OneDrive account is locked. My OneDrive account was locked by Microsoft due to exceeding its storage capacity. The solution is to purchase a larger OneDrive storage capacity, for example, 1TB, and then wait for your account to be unlocked. Finally, return to the initial screen, and you will be able to see the recovery key.
