    Roblox app won't open. 0xc0000409


    I'm having an issue with Roblox on Windows 10 Pro. I am using the latest windows version. When I try to open Roblox it wont open. Roblox Game Client shows up in Task Manager for ~3 sec and then disappears. Same problem have Roblox Studio. All other apps/games works very good. What I tried: Completely uninstalled and reinstalled Roblox, updated Nvidia graphics driver, restarted my computer, fully shut down computer SHIFT+Shut Down, ran the DISM tool, Clean Boot, installed Microsoft Visual C++ 2012, 2013, 2015-2022. I dont have Antivirus app. I have good WIFI/Internet. I tried to install Micro
