Description

In loading a .NET dll, I get a SystemError that does not come out when compiling with ipyc. See code below.

Steps to Reproduce

Code used in file testIPY.py

import clr
# import my api
clr.AddReferenceToFileAndPath("myClass.dll")
import myClass
tt=myClass.API() # instance of my object
print(tt.version()) # return version
input("Press key to close...")

1. if I run ipy testIPY.py I get:

Traceback (most recent call last):
  File "testIPY.py", line 6, in <module>
SystemError: L'inizializzatore di tipo di 'myInnerClass.innerClass' ha generato un'eccezione.

2. if I compile with ipyc /main:testIPY.py /target:exe, I can run testIPY.exe flawlessly. Output is:

1.00000000000001
Press key to close...Error occurred: unknown encoding: cp850

Version Information

If you are using the ipy console program, provide output of executing ipy -VV. If it is a local build, provide also the git hash of the commit used to build IronPython. Additionally, provide the type of the operating system used.

ipy -VV
IronPython 3.4.1 (3.4.1.1000)
[.NETFramework,Version=v4.6.2 on .NET Framework 4.8.9181.0 (64-bit)]

Ufortunately I cannot share the DLL, which is obfuscated. Debug DLL does not exhibit the same problem.

Start with the testIPY.py reproduction and compare running it through ipy with compiling it through ipyc using the reported commands. Investigate the differing behavior around loading myClass.dll and the myInnerClass.innerClass initializer; the missing obfuscated DLL limits direct reproduction. Done means the script behaves consistently in both modes, with the reported SystemError and encoding error addressed or clearly explained.
