dynamiclink media server not available

I use Photoshop CC 2015 to make animated gifs from video clips. To do this, I use the import video frames to layers function. However, yesterday when I did this, the "Initializing video import" loading bar came up and stopped at 80%, and then the program stopped responding. When I closed the program with task manager, an error popped up momentarily saying "could not complete your request because the dynamiclink media server is not available." I get the same error if I try to open a video with File > open, or load it into the timeline, or drag and drop it into Photoshop.

I've spent over 5 hours now scouring the internet for ways to fix this. I've found others with the same problem but nothing that fixed it for them seems to work for me.

I have the most recent Windows 10 (the April update), my display driver is fully updated. I even downloaded Photoshop CC 2018, the most recent one to see if an update in that fixed it, but it had the same issue.

My graphics driver is Intel(R) HD Graphics 520.

I also tried rolling back to the last Windows update and previous graphics driver updates to see if an update had somehow broken it, but it didn't work.

I have tried restarting my computer multiple times. I also followed all the steps in the graphics related FAQs on this website, and nothing. I tried renaming the sniffer file. I tried deleting the Trace Database txt file. I tried disabling my firewall.

It's worth noting that on startup, sometimes I get a message saying "Photoshop has encountered a problem with the display driver, and has temporarily disabled enhancements which use the graphics hardware."

Any help is greatly appreciated... This is extremely frustrating and I'm about ready to give up and accept that I'll never make gifs again.
