Sql CLR runtime error

Doing a SQL CLR. Everything worked great in development, everything whent great in testing, then we went live, and everything broke. So it seems to have something to do with EXTERNAL_ACCESS security. I have confirmed that our database is marked as trustworthy, the database owner is a sysadmin, and the assembly is marked as EXTERNAL_ACCESS permissions. That leaves me a bit stumpted as to what could cause this error. Any other ideas on what could cause this error?

(I hid a few things that arnt critical to the error)

Error querying repository for dirty items: 'prc_XXXXXXXXXXXXXXXXXXXXX' System.Data.SqlClient.SqlException: An error occurred in the Microsoft .NET Framework while trying to load assembly id 65536. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error: System.IO.FileLoadException: Could not load file or assembly 'myassemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=123451234151234' or one of its dependencies.

For some reason, even though the UI showed that the assembly had external access permissions (and it added to the database with those permissions), internally it must have thought that it didnt have that kind of access for some reason. So as a work around I ran these commands and it fixed the problem (note I tried running just the second command, and it didnt fix it):

ALTER ASSEMBLY [< AssemblyName>] WITH PERMISSION_SET = UNSAFE

ALTER ASSEMBLY [< AssemblyName>] WITH PERMISSION_SET = EXTERNAL_ACCESS
