Hi ,
I recommend not trying to delete the default package folder for reinstallation. If you try to reinstall, there's usually no saved data, just the native installation package that comes with Windows.
If you've already uninstalled the program, just ignore the packages folder because changing these folders can corrupt the Microsoft Store permissions settings, causing it to stop working. I've already tried this. If you've already uninstalled the program, keep the native installation folder untouched.
If you want to delete the folder, go to Properties > Security > Advanced > Select Security Principal > Advanced > Find Now > Select your user, add > OK, select Full Control, and apply.
Do this only in the ClimpChamp folder. Remember, there's a risk with Microsoft Store appxs.
Give feedback if the information was useful or not.
Thanks
