Error : Extension jar(s) were not found in lib/common directory of the extension

[VG_8323155]

We are unable to access Thingworx composer after windows server updates and getting error "Extension jar(s) were not found in lib/common directory of the extension" in application log. The service stop automatically whenever we try to start it.

The application was running fine and we didn't performed any major changes except windows updates.

Can you please help us to find/resolve this issue? Why it occurs and how to resolve this?

ThingWorx Version : 9.3.5 (Postgres)

Thanks for the reply, but above solution doesn't work. I am really not sure this as it was logged as Warning message. For better understanding, I have attached the standard error log file of tomcat. Requesting you to please check and let us know your valuable inputs.
