Windows 10: Windows Explorer randomly stucks lately

From time to time Windows Explorer gets stuck, and the taskbar becomes black, and I am unable to get it working again unless I restart (ending task / restarting the explorer from the task manager won't work either)

I did install an SSD lately (6 months ago) and maybe it is the culprit
What checks do I need to do in order to better isolate the problem? perhaps chckdsk? does it work on SSds? or how to check for SSD bad sectors/ defects?

It's a SanDisk SSD and the software from SanDisk says it's 99% healthy, but that says nothing about possible sudden death, it's just how much writes do I still have left in theory

Or any other causes?

Error: "To use System Restore, you must specify which Windows installation to restore. Restart this computer, select an operating system, and then select System Restore" on Windows 10

So has anyone else's PC been f***ed lately? Mine just randomly decided to bluescreen three times and then refused to boot beyond BIOS. I'm trying to restore with wbb05's method now... For the moment stuck using Kali from a thumbdrive
