Hello 新倫林,
Thank you for posting in Microsoft Community forum.
1.Could you please provide the detailed error message about "red "Certificate error" message"?
2.Based on the description "I reinstall Edge to version 121.0.2277.128 , this way is ok.", do you mean if you install such certificate on ***Edge with version 121.0.2277.128, there is no Certificate error?***3.Is your machine in domain or workgroup?
4.How did you get the certificate that installed in the Edge?
5.Can you use Edge and any websites normally? I mean whether red "Certificate error" message affects Edge and any websites?
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
