I am using Windchill PDMLink Release 12.1 and Datecode with CPS 12.1.1.2

MethodServer报错，无法登录Windchill系统。MethodServer报错日志如下：

This could be a tuning issue: https://www.ptc.com/en/support/article/CS297624?source=search

Do you have a lot of types or cascading attributes?

The error message is not related to Login operation.

Make sure the Methodserver is ready,  attache the full Methodserver log and the screenshot of the error message when failed to login to the system.
