disassembly failed. Error: 80004005 no matter what I do

There is not a single setting which results in a different output than these, -v does not provide more information, PixelShader.xnb is in the same folder as cmd_Decompiler.exe, but having it in a different folder and providing the path did nothing but add that path to the error message, and using a .cso file from an xnb unpacker similarly did nothing but change the file name of the resulting error message:
Decompiling PixelShader.xnb...
disassembly failed. Error: 80004005
