Screen blinks at the “Language” step

Hello everyone, I encounter a problem while trying to install macOS Big Sur on my Lenovo laptop (specs below). When the “Language” window comes up, it stays on my screen for like half a second, I have a black screen for 10 seconds or so, and it shows the “Language” screen again for half a second and this repeats indefinitely. I tried to plug my laptop to an external monitor but nothing shows up. Do you have any idea concerning the reasons of this behavior? Thanks.

Specs: - Laptop: Lenovo IdeaPad 330-15ICH (81FK) - CPU: Intel Core i5-8300H - RAM: 8 GB DDR4 - SSD: NVMe 128 GB - HDD: SATA 2.5” 1 TB - iGPU: Intel UHD 630 - GPU: Nvidia GeForce GTX 1050 Mobile (disabled in BIOS)
