I had something similar happening in hyprland when I turn off one of my external displays using dpms off: the display would do some sort of reboot and reconnect: when this happens while swaylock is active, on the second reboot of the screen, swaylock would crash with a red screen.
This only happened to me with one of my external monitors, not with the others which is strange. On my side I think the issue can be fixed with a debounce timeout on the dpms off command, which is not related to swaylock. I hope that this information could help you trobleshoot your issue

@manu0600 do you mind popping into hyprwm/Hyprland#4134 and sharing your findings? Seems they're discussing a similar issue
