thanks for the analysis reports – it looks like the camera isn't switching into HGC mode when run at full resolution (there's no clip in the read noise like there is at the old full resolution). The read noise is – give or take – about half the value at low resolution, which would be expected.
On the crash when you are trying to use the focus tools, I think I found the uploaded crash report and it looks like you are using a Celeron J4125 CPU. Unfortunately CPUs of this age don't work with the 64-bit version of SharpCap – SharpCap 64 bit requires a CPU that supports the AVX/AVX2 instruction set. In theory those instruction should only be used if they are available, but with the 64 bit version it tries to use them for some memory housekeeping tasks and try as I might I have been unable to find a way to stop it

Unfortunately, that leaves you stuck to some extent, since the 32-bit version will work fine but may hit memory problems with such a high resolution camera. The 64-bit version will work for basic capture, but anything that relies on image processing (like focusing or live stacking) will fail.
Sorry about that, Robin
