patch failed

the log files are not the ones I think, since I don't have a "logs" folder:

when trying to manually downgrade the version of the game, the patcher gives an error:

when using the installer, it also writes that there is a problem with the patch:

I turned off the antivirus, started it as an administrator, reinstalled it.NET

always the problem is in the patcher

PS: the problem with "a patch failed to apply" and "failed to decode file delta" has not been solved yet
