Hi,
We discovered an issue that impacts feature extraction during step 1 in the latest version of Pix4Dmapper (4.3.31).
Some users may experience a crash while processing with the GeForce GTX 10 series NVIDIA GPU.
We recommend following the Pix4D Desktop release notes which we will update if there is any new information regarding this matter.
In case you currently face this issue, we recommend reprocessing the project or processing the project with your CUDA GPU disabled.
You can disable your NVIDIA CUDA capable device in the Resources and Notification tab in the Processing Options window.
We will keep you apprised of the situation,
Best
