Please tell me what is the reason for this error. It is no longer available and reinstalling is useless.

OSError: [WinError 123] The filename, directoryname, or volume label syntax is incorrect. : '"G:'

this most likely means that you no longer have a "G:" drive on you system.
this could be because you removed or added a hard drive or removable drive (USB drive)
the simplest fix would probably be to clone the project into a new folder and copy over your models and stuff.
deleting the venv folder and repositories folder probably won't fix anything, since the broken link is probably in a config file.
I would avoid copying any of the config files, as the broken link is probably in one of them.

Thank you, I have solved it by reinstalling the system
