Hello my friends, im new in this community, recently i bought the game Little Nightmares, i tried to play it fro the GOG Galaxy App, but it doesnt launch.

I have a new Acer Nito 5, i dont know what my problem could be

I was having this issue as well. Rebooting would fix it for a few days, but then it would start crashing on launch again. What seemed to be causing it for me was an apparent conflict with either DS4Windows or NordVPN, both of which I have startup with Windows. I'd usually close DS4Windows before playing LN since it has native DualShock 4 support, but I'd occasionally forget. On a whim, I tried closing both programs after the game failed to launch again, and it launched fine right after that without having to reboot. I never got around to confirming which program was causing it, but it was probably DS4Windows if I had to guess. If you don't use either of those programs, then it could be something else. Also, try reinstalling the necessary Microsoft Visual C++ runtimes.

Good luck and welcome to the community!
