Check inside task manager while DPP is running before trying to edit to see memory utilization and processor loading. You should have plenty of memory with 16 GB but if something odd is going on with your computer something may be grabbing most of the CPU or memory resources.
I recall in an earlier version of DPP, it would crash upon loading because the folder had some other files in addition to RAW. That has been three years ago and I can't recall now what type the other files were but removing them cured the issue and I had to do this because DPP would crash before I could change directories. I now set up DPP to open to the blank top level of the directory that stores files in subdirectories by shooting date.
I have been running 4.10.40 for a few weeks now and it seems to work a little better than the prior version although there is still a bit of a memory leak that shows up after some time slowing performance even though it is only using a very small percentage of available memory. I am running it on a HP Z820 dual processor workstation (Win 10) with 128 GB per processor and after about an hour, total memory utilization by DPP is in the 3 gig range and performance slows. Exiting and restarting allows it to run at normal speed for another hour or so.
With enough resources it handles a large number of files easily until the memory leaks grows large enough and after a full day of soccer games I will have a few hundred RAW files from my 1DX and 1DX2 in a single directory with no crashes. My only continuing complaint is it can be a little slow when running digital lens optimizer followed by other file adjustments. During the time it is processing, CPU utilization stays below 10% and GPU utilization is also below 10% so it is spending a lot of time doing stuff but it isn't heavily utilizing resources. Running digital lens optimizer and other corrections isn't much slower with my HP Zbook 17 even though it only has a single 4 core I7 processor and 32 GB of RAM compared to the twin 8 core processors and 256 GB of RAM in the workstation. Both have Nvidia graphics but the workstation has far more CUDA GPU units available and DPP is set to use the GPU on both systems. DPP doesn't seem to do a very good job of using available resources; by comparison when rendering a 4K video using Corel video editing software on the workstation all 16 cores are very heavily loaded.
