I couldn’t find the answer for a long time, so I changed my gmail account and it worked. It should be an account problem. After logging in with that account, I found that gmail prompted me to limit sending emails;
Official explanation:
Sending restrictions
If you send a message to more than 500 recipients or if you send a large number of undeliverable messages, Google will temporarily disable your account in order to prevent spam and avoid abuse as much as possible. If you're using a POP or IMAP client (such as Microsoft Outlook or Apple Mail), you can only send messages to 100 recipients at a time. Your account should be reactivated within 24 hours.
If you communicate with the same group of people on a regular basis, you might want to try Google Groups.
If you send a large number of undeliverable emails, we recommend that you confirm your contact's email address. It's also crucial that the person you're emailing wants to receive your email.
