Thanks for the extra information and sharing the log file.

The log indicates there was an error during the frame encoding process. There is no indicator of where the issue may be occurring from, so Please try doing all of the following.

First save a copy of the user library folders before proceeding if you have any saved assets you do not want to lose.

  1. Delete the entire folder 2023.1 in Documents C:\Users\&username%\Documents\Twinmotion2023.1
  2. Delete the logs and temp folders.
    1. C:\Users\%username%\AppData\Local\Twinmotion
    2. C:\Users\%username%\AppData\Local\Temp\Twinmotion2023.1
  3. Run the Prerequisites .exe. C:\Program Files\Epic Games\Twinmotion 2023.1\Engine\Extras\Redist\en-us\UE4PrereqSetup_x64.exe
  4. Then verify the installation from the Epic Games launcher.
  5. Restart computer and try again.

This should remove and reset all Twinmotion files in case the issue is caused by corrupt Twinmotion files. If that does not fix the issue, please try checking your Windows Update for updates to system drivers that may need to be installed. Particularly, try checking the video codecs for updates, or re-installing them.

Let me know if this helps or not.

Best,

Raghib
