MacOS Catalina Stuck at Estimating time remaining before the end of the progress bar.

[MetalBasket4236]

Hello, I am trying to install Catalina on Proxmox But After the first restart at the apple logo and the progress bar, the progress bar is stuck before the end and just says "Estimating Time Remaining..."
Any help is appreciated.

(Note: Unfortunately I don't have a screenshot of it.)
