Thank you, @Brecht Van Lommel (brecht), commit c8fc23fdbe0 has fixed the reported issues with the materials tab along with the lookdev and rendered display modes..

Can confirm this (T63698) and T63760 are related (or were at least broken in the same commit I guess would be better wording). As promised, I just got done doing a bisect search, and every time that clicking Materials caused a crash, selecting either Rendered or LookDev display modes would also cause a crash. They also both give me the exact same error output from the debug cmd scripts.
I was browsing through and found this thread. I reported the same issue here a couple of days ago. I did not find it initially, but I mentioned it in a comment a little while afterwards.
@Sebastian Parborg (zeddb) I just wanted to let you know I haven't forgotten, but as I do C# programming I don't have the C++ workload downloaded for MSVS 2017, and my connection isn't exactly the fastest. But I will try to get it done over the weekend.

@Sebastian Parborg (zeddb) Oh yeah, pretty sure I watched a video on that. Downloading the libraries now, and I have some stuff I need to do this morning, but I'll give it a shot later today or sometime tomorrow and report back. :)
@Sebastian Parborg (zeddb) Well, I do some programming myself and I found the step-by-step guide on Building Blender on the wiki, fairly confident I can do it. My knowledge on git however is pretty basic, not sure about my ability to do a bisect search.
@Sebastian Parborg (zeddb), yes, I am.

Continued to play it a bit and found that hitting Z and selecting Rendered or LookDev display modes also crashes the program. I replicated this using the same blender_factory_startup.cmd script, and all 3 seem to generate the same output in the blender_debug_output.txt file. I know I had no problems with the Rendered display mode in the previous build mentioned above.
