Crash: Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000000

Good day, I just install 5.7 but when I tried to open any new window, it will starts to distort like crazy, occasionally comes with yellow + pink screen, then after 10 sec it will just crash with the title. This affect any 5.7 related from launcher to projects

Here are my specs

CPU: 12700K

GPU: RTX 5080

RAM: 64GB DDR5

OS: Windows 11

Note I have 5.5 and 5.0 installed and they both works fine, I tried:

  1. Update drivers for cpu,gpu and windows, didn’t help
  2. Verify the entire version 3 times, plus a complete reinstall, didn’t help
  3. Saw a comment says shut down RTX Video Enchanment, didn’t help
  4. Saw a comment says turn off Nvidia and Discord overlay, didn’t help
  5. Saw a video about adding entries in the Registry Editor, didn’t help
  6. Change the local config file or DefaultEngine.ini, didn’t help
  7. Delete or readd the Cache and Intermediate file, didn’t help

Changing the DX version should help almost 100%…
Or at least the crash message should have a different version of DX :roll_eyes:

But this may also have little (nothing (?)) to do with launcher problems…

It helps, but now it only solves the crashing but not the distortion.

I took a bit of redigging, apparently this was caused by Nvidia’s Smooth Motion settings (Graphics > Global > Smooth Motion), just turn it off fixes everything.

Thanks anyway
