Problem after installation UE 5.2 - external drive

Hello,
I just installed the latest version of Unity Engine 5.2 on an external drive. After closing Epic Games Launcher, the drive was unmounted for a while. After plugging in the disk and returning to Launcher, I have non-stop info Not Installed. The location where the installation took place is not visible at all, although there was a choice at the beginning. Where in the settings can I change something so that the very time-consuming installation does not have to be done from scratch. Does Unreal not work on an external drive?

I’m using a Macbook Pro M1 and everything is the latest I need.
Thank you for any help
