After the EMCLIENT client jumps to the web page GMAIL login verification, it always prompts OAUTH credential error. In addition, adding other email accounts is also difficult. It took me several hours to add 4 email accounts. I don’t know what caused it. The operating system is WIN11.

Yes to add a Gmail IMAP account you use the “automatic account wizard” as per the eM Client Google Workspace page url link below where “at the end of the wizard” you get a browser prompt to allow eM Client access to your Gmail account with an OAuth token which then normally goes back to eM Client and start receiving mail.
If you press allow and nothing happens, then “try completely clearing your browser cache” and then close your browser and then close and reopen eM Client and try adding again.
Failing that “try setting another browser as default” as could be your current browser.
If you still have the same problem, sometimes optionally installed background resident programs can interfere with the authorisation part in your browser such as eg: optionally installed Firewall / Security programs, or optionally installed Antivirus programs etc, so if you have anything like that installed “other than what comes default with your OS”, try completely disabling those to test.
