Problems with Multiple Windows, Soundbar, and Media Playback

My problem is kind of complicated to explain, but all of these minor issues began happening at about the same time. It began happening more than 10 days since my last update, so I can't revert easily to older versions, and I've already tried doing a soft reset on windows. I'm using the newest release of windows 10, and I've run malwarebytes scan.
So my issues are as follows:
-When dealing with multiple instances of one program that are grouped on the taskbar, I can't open minimized instances by mousing over the group and selecting that window, the windows show up when I mouse over them on the taskbar, but when I click them, the windows just flicker and won't actually open. I can, however alt+tab into any instance.
-When I put my PC to sleep, it automatically wakes itself randomly within 30 seconds of me putting it to sleep and remains on the sign in page
-When I have spotify open, the sound bar at the top left (that indicates the program playing sound and the volume) will not go away unless I close spotify, additionally, when using a wireless keyboard any time I press any key that sound bar comes up for a few seconds whether I have spotify open or not and the media volume keys don't change the volume. I don't use that keyboard now, and have the dongle out of the USB port because of this, as it doesn't happen on my main wired keyboard.
-Spotify won't play back any music, pressing play does nothing on the app and it appears not to actually load the song, however I can play back music on the web browser version of spotify, and audio playback works fine generally in the browser.
-VLC media can't play any video files, it just glitches out when I open them, however Windows media player can play these files. I also have some issues on video playback in my browser intermittently where the video will play back too fast or the loading/playback bar will glitch around.

Those are all the separate issues that happened at the same time, and I had no problem with VLC Spotify, multiple windows, or my wireless keyboard before a week ago, and windows would only wake from sleep with a mouse click or key press.
I looked up how to fix the volume bar problem originally, and it was suggested that I do a reset on windows while keeping my files, so I tried that with no success.
