decompiling

Tell me how to adapt the Luadec decompiler to LuaJIT scripts One guy somehow decompiles LuaJIT scripts using this decompiler, but doesn't want to say how LuaJIT 2.1.0-beta3 >luadec Fram.luac luadec: Fram.luac: not a precompiled chunk

I want to take .exe/.dll, where async/await was used in the source code and see what the compiler generates there. See with y ... piler generates for async/await? P.S. tried on .NET Core 3.1 and on the latest version .NET Framework. I work on Windows 10.

In general, I wrote a small script for in python. The customer demanded that there was a ready-made exe, so I had to use Pyin ... a flash drive. Tell me if you can somehow decompile them in .py or mb some other solution (writing again is not an option).
