When booting with intel graphics (enabled through prime-select), the computer freezes rigth after selecting 'Kubuntu' in GRUB

[Simão Santos]

After booting with Intel graphics enabled, the Kubuntu initial screen appears, then the Lenovo screen.
After about 5-7 minutes in the Lenovo screen, it shows the following message (https://imgur.com/a/NO8O1qL), which adds a new one after increments of 2 minutes, .

When changing to the patch '18', the computer functions normally, allowing me to change to the NVIDIA graphics and that's where I'm able to boot to my normal setup, in patch '42'. The same happens in patch '40' by the way.

The strange part is, a few days ago everything worked out fine. This first happened when I changed from NVIDIA to Intel (through prime-select, as usual), and instead of restarting the PC through the button in the UI, I used the 'reboot' command in the terminal.
I have also previously noticed that restarting my computer by the command is slower when comparing to clicking the button.

Thanks in advance for any help!
