As title, unity changed the way the builds export so the folder names have changed giving errors about invalid characters.
It works removing the “:” but that breaks player prefs and changes the app name.
The player prefs changing is a huge issue as currently players will lose things like login credentials/settings/progress.
Did you report this as a bug? If not, please do so.
Hey I believe you are running into this, a fix is coming: Unity Issue Tracker - Building fails with the error " The directory name is invalid:" when ':' character is used in the Product Name
