ModuleWriterException: Invalid section RVA #545

Open Drovosek01 opened 9 months ago

Drovosek01 commented 9 months ago

I'm exploring. A dll file compiled using dotNet on a Mac with Apple Silicon processors.

I open the file in dnSpyEx v6.5.0 and then just try to save the module without any modifications

and I get an error:

I tried to do this on Windows 10 x64 on an AMD laptop, and also tried to do it on Windows 11 ARM via Parallels Desktop and always get the same error.

Does anyone know how to fix this? Here is an example of such a file: CsvHelper dll for arm64.zip
