Create Project

Hello,
when i creating new projects in Unreal Engine 4.19.2, I keep getting the message that the folder is write-protected.
There is no write protection under the folder settings. Nevertheless, the same message keeps coming back. I cannot create a project.
Photos attached.
MacBook Pro (15 inch, 2016)
macOS Catalina version 10.15.7
Many thanks in advance.
Kind regards
