I cannot install Cyberpanel on my server!!

I tried to install Cyberpanel on my server, but when it was almost finished, a black screen suddenly appeared with a white dot in the upper left corner. How can I fix it?

My server configuration:
CPU: Intel i5-10400
RAM: Crucial 8GB DDR4-2666 (8GB*1)
MB: ASUS Prime H410M-K
GPU: MSI GT 1030 AERO 2GD4 OCV1
OS: Ubuntu 20.04 LTS

Thanks:-)
