Launcher doesn't start (Error code 0x1 or 0xc000005)

After installing the launcher, the Minecraft Updater starts downloading update files. After that, starts “Cleaning up” and closes without opening the launcher. When I open ut manually by pressing “Play” on the Store, the game fails to log in with error code 0xc0000005. In other cases, it closes even faster with error code 0x1.

After the Updater closes, I found these logs in the launcher_log.txt file in the .minecraft folder:

When the game crashes, I checked again and this is the last line it logs:

I also tried deleting the .minecraft folder manually and opening it again, but it still didn’t work.
