Did you manage to solve this problem? I'm running v188.8.131.52 and everything works in dev and test, had an initial deploy uploaded to the production environment which ran just fine.
When publishing the latest code to production i get the same error as you.
Tried setting up an new site with production files and database which worked oob.
Is there any error message in log files?
I had the exact same error.
EPiServer version 9.3.1
Windows Server 2012 R2
Deploy to production worked fine the first time and then stopped working two days later.
A restart of the production server solved the issue.
I would guess that temporary asp.net files is messing things up. Try deleting those...
Happens from time to time...
Cleanup of temporary asp.net-files did resolve the issue only to rise again, the main problem was with a couple of wiindows updates.

I can login to the CMS on my local site running EPiServer 184.108.40.206. Edit mode works without any problems but when I try to go the Admin mode I get this:
External component has thrown an exception.
System.Web.HttpCompileException (0x80004005): External component has thrown an exception.

Anyone knows what causes this problem?
I should mention that the application worked fine before but suddenly started to show this error message. I have tried to restart the IIS, removing ASP temporary files and even starting the machine but none of them helped.
Thank you in advance,
