Unfortunately this sounds like probably a hardware or driver issue and it may be hell to solve.
But it looks like your Event Viewer may hold some clues. Although most events are incredibly vague, sometimes they do contain useful information. You should go through that summary page and look at any events that happened recently (especially those in the Critical section or Error section. When you double click one of those lines in Event Viewer it will bring you to a filtered view showing the type of event you double-clicked. When you're done reviewing those events, you can use the back button in the upper left to go back to the summary view.
Kernel-Power events (which you had twice in the last week) occur when Windows boots up after an unclean shutdown (which could be intentional done by you, or the result of a power outage, or hardware/driver-caused crash).
The DriverFrameworks-UserMode events are something I haven't seen before, and with any luck they correspond to your Remote Desktop failures. Hopefully in the event data there will be some indication of which driver is having a problem and what the problem is, as this could indicate you have some failing hardware causing issues. Could be anything from some onboard component to a USB-connected device and it certainly could be involved in causing the problem you are having.
The nvlddmkm error is associated with your nvidia GPU so it would not be a bad idea to get the latest nvidia graphics driver. However with only one occurrence in the previous week I doubt it is the cause of your remote desktop issue.
Also check out the Application Hang line in event viewer and see if you can tell what that is about.
Also, if your system happens to be maxed out on CPU or RAM usage while you are trying to connnect with remote desktop, that could aggrevate the issue. High enough memory usage may even cause apps like remote desktop to fail to load correctly and crash. You should be able to monitor this remotely via
Blue Iris's web interface (UI3) or mobile apps, and if memory usage is very high (like above 90%) then it could be a possible problem for you.
