Windows 10: Support For Old Windows Apps Dwindling After Update 2004?

Before the 2004 update, I was able to run WinQuake at 720p, 60FPS, Quake 2 through Yamagi Quake 2 at 1080p, 60FPS, Quake 3 through Spearmint at 1080p 60FPS, Unreal Gold using the "Old Unreal" patch at 1080p 60FPS, Unreal Tournament 1999, and Unreal Tournament 2004, at 640x480 highest settings 60FPS, and Half-Life at 1080p 60FPS with the low graphics option disables anti-aliasing. For some reason, when I updated to Windows 10 2004, these apps no longer work properly. I have tried reinstalling them, changing compatibility settings, and a number of other troubleshooting tasks. Sometimes Windows would complain that the version of DirectX used for Unreal wasn't compatible with something, other times it would run fine. I forgot what it said because I uninstalled all the old Unreal Engine games I had. Quake won't give me the option to select 720p anymore, and running Quakespasm, or any other source port will have Windows complain that OpenGL isn't supported, or it will run, but damage and power overlays cause the framerate to tank. screen tinting red, blue, or gray causes framerate to go from 60FPS to 10FPS or 3FPS for some reason Yamagi Quake 2 will frequently crash for no reason, or Windows will complain about OpenGL. Spearmint Quake 3 randomly crashes for no reason, or will complain about OpenGL. Half-Life will either run fine, or complain about OpenGL, or even software rendering for some reason. Software rendering works fine for the most part unless Windows is having a bad day, and I need to restart Windows to get the game working again. There isn't just problems with the older games I have either. I frequently play VRChat, and when post processing is enabled mainly color tinting, or bloom which used to run fine in 1909 the framerate takes a massive hit. From the looks of it, overlay effects have the biggest problems. I even used to use a PlayStation 1 emulator because my PS1 broke, and this was the only way for me to play those old games, and now ePSXe thinks I'm using a 64bit ARM processor even though I have an X64. My system specs: Core i3 7th generation @2.4GHZ, Intel HD Graphics 620 1GB VRAM, 8GB of unknown type of RAM, 1TB Hard Disk Drive, 1 external 4TB SSD, Windows 10 version 2004. Did Windows change the way it handles Graphics APIs? If anyone can help me figure out how to get compatibility back, that would be nice. I cannot go back to the previous version of Windows because the previous install was deleted either due to a bug, or the previous install becoming corrupt. To make things clear, none of these problems had occurred before the latest update, these are new to 2004.
