Welcome back to the Community!
In the case of this ucrtbase.dll , the issue could be caused by a conflict in the ‘proj_lib’ environment variable. Pix4D uses the GDAL library. If GIS-related software is installed, which also sets an environment variable ‘proj_lib’, after removing the environment variable, the issue could be resolved.
For more information:
