Exception type: TargetInvocationException in EPiServer 9.9.1

Vote:
 

We recently upgraded from 7.15 to 9.9.1 version 

When we re-start our servers (Windows2019) hosting our episerver websites, the CPU usage goes high (100%). When we checked event viewer we saw below exception logged multiple times. 

Exception information:

    Exception type: TargetInvocationException

    Exception message: Exception has been thrown by the target of an invocation.

Any ideas what might be causing this error and how we can fix it?

It almost looks like you're missing an inner exception. Anything thrown to the log file of your website?
