Just an FYI - in the new version, only on my surface (though I have the same definitions as on my desktop), contextmenu64 is being detected as a trojan by windows Defender. I did submit that to microsoft.

I was going to suggest, before I read your post, to try disabling your anti-virus, temporarily, to see if that solves the problem with XYplorer locking up.
I do recall that some anti-viruses tend to disable access to files until they have been checked, regardless of whether you are opening/running them or not, which used to cause big issues on one of my older machines, due to shortcuts to apps containing servers on my taskbar (things like TightVNC, various P2P apps, chat servers, etc.). The entire taskbar would lock up for the longest time, as their icons were loaded. Also caused problems in Explorer, whenever I opened a folder containing a .rar file. When I temporarily disabled my anti-virus, the problems stopped. So, my solution was to ditch McAfee and install a lighter anti-virus, which at that time was AVG. It was a lot less aggressive, only checking files when I tried to actually access them, rather than how McAfee was checking every file shown in an Explorer window, regardless of whether I was attempting to open/run them or not.
If your machine is a little slow or your anti-virus a bit too aggressive, it could very well be causing a lockup situation when XYplorer accesses a large number of files, so it can display their information to you. The accessing of them does take a little time, to begin with, which could then end up immensely magnified by the anti-virus temporarily denying access while it checks both XYplorer and those files for malware, first.
So, try disabling your anti-virus and see if it helps.
