Oh man… this problem gonna kill meeeeee! i cant do anything. i even waited like 20 min but nothing happens. deleted and installed again unity but didn’t fix. is anyone know to how to fix?
Do you have your project in any kind of cloud? Like Dropbox, GoogleDrive, OneDrive (…)?
You should not do that, because you will very quickly run into the issue that the cloud and Unity want to access or modify the same file, which basically leads to both applications getting stuck.
In conclusion, make sure your project is saved in a location that does not get synchronized with any cloud, and use some kind of version control for your backups, like Unity Collaborate
