Error in magic number when converting pyc python code to py source code

I tried to use a tool called easy python decompile and websites to convert pyc python code to source (.py) again, but I have got an error in magic number.

Also, I tried the following commands using command prompt using pycdc.exe:

pycdc.exe OSV_Main.pyc

I got a little part of my source code and then stopped with the following error:

Error decompyling OSV_Main.pyc: vector::_M_range_check: __n (which is 32) >= this->size() (which is 20)

Please refer to the screenshot of the error: 1 and 2

How can I retrieve all the source code as the version of python I used 3.11?

Looking at the error in your screenshots from that disassembler, I see:

Unsupported opcode: BEFORE_WITH

I also see that you are using python 3.11.

Taking both into account it happens to be the case that this opcode is new in version 3.11

per: Disassembler for Python bytecode

and it looks like your disassembler has just not caught up with 3.11 yet.
