Heya! Since you used the last version, take a look at the solution in this thread. Hopefully that helps you! https://itch.io/t/2275817/not-responding
It sounds like this might be an antivirus/firewall issue, since you also mentioned that it is deleting the exe. Check if you are able to add vtuber kit to an ignore list. The only other thing I could think is maybe it didn't extract correctly? Could possibly try unzipping using a different archiving program.
