This PR fixes #6929

@kozlovsky:

I debugged the problem and found the reason for the error. It is in this line of CoreManager:

self.core_process.start(sys.executable, core_args)

There is a difference in arguments between a python script and a compiled executable. For script, arguments can look like

["myscript.py", "arg1", "arg2"]

and sys.executable is something like C:/Python39/python.exe.

For the same code in the compiled executable, arguments will be

["myscript.exe", "arg1", "arg2"]

and sys.executable is myscript.exe.

That means that when Tribler executes self.core_process.start(sys.executable, core_args) from the compiled binary, it runs tribler.exe with arguments ["tribler.exe", "some.torrent", "--core"], because tribler.exe comes both from sys.executable and from sys.argv[0]. The proper fix, in my opinion, is to remove duplicate "tribler.exe" from the argument list when running a code from compiled binary.

So, the reason for the error is that when compiled, GUI runs Core with arguments:

tribler.exe tribler.exe some.torrent --core
