What is your ArcGIS Pro version? Have you checked the compatibility between it and FME? Notes on FME and Esri Versions and Compatibility

Thank you for tips.

Yes, ArcGIS Pro is in 3.3.1, that is compatibility with FME.

There is no problem before, I think the reason could be the new Win11, but no idea about how to slove it.

Even though its truncated, does that DLL actually exist somewhere in the plugins folder?

I’ve had experiences in the past where overzealous security policies have cleared out portions of the libraries used by FME

You are right, the DLL file is missing. Do you remember how did you fixed it?

I have this file in FME 2023 version, can I reuse it? and the sde in FME 2023 is no longer can be used anymore.

Hi ​@fiona1112 
To Summarize on your system you have the following 
ArcGIS Pro 3.3.1 
FME 2024.1  
FME 2023.x (previously installed) 

After upgrade, Esri formats (ArcSDE and File Geodatabase) are not enabled. 
Previously working with FME 2023 

I would require additional information to try to troubleshoot this further. 
Did you upgrade only FME or ArcGIS Pro as well?
Do you have multiple Esri application installed on your system i.e. ArcGIS Pro, ArcGIS Desktop etc? 
Have you review this article to ensure that you have met all dependencies? FME and ArcGIS Pro
Is ArcGIS Pro using Named User license or Floating? 

Also if you have any Antivirus or other software that may be blocking the access to the FME.

We had to reinstall the software, after working with IT to ensure the files wouldn’t be flagged/removed again

Only FME was upgradetet this time, and I have only ArcGIS Pro with Named User License i my system.

I suspect that because the strict IT policy. Thank you for suggestion :).
