Hi georgemelkadze,
Sorry to hear that you ran into this problem again 
The problem does not happen to other clips and other scene files? Also, please make sure the available drive space is enough.
We want to test and recreate this error if possible, therefore, please send the scene file and the video you rendered (which has the problem), and two folders containing logs, to my email ziyin.zhu@d5techs.com
- A folder called logs, in the installation directory of D5 2.2
- A folder called Saved, in C:/Users/your account/AppData/local/d5_immerse
We will look into it and keep you updated here.
