Hi @weinian1985,
Thanks for the information. We have some more questions before letting you know how to proceed.
Did you migrate your Mantis installation from Windows 7 to Windows 10 or did you upgrade the operating system in the machine where Mantis was installed? I assume that Mantis was working properly before this upgrade process, right?
I found many errors in the database's log

Did you perform any action in the database before running into this issue?
Thanks
