It sounds like you hitting a full drive issue, your symptoms line up. One of the issues this series encounters is running on its limited RAM it needs to use the drive for virtual RAM. So when you have a full drive the needed space the OS needs is not there! Clean off a good 1/4 of the drive that should stabilize things. But, you have a hidden problem running your system so tight. Your SSD drive needs to even out the wear (wear leveling) in this connection you tend to over wear the drive so you might be at the ned of life on your SSD. You’ll need to get a utility to check it here’s more Monitoring SSD wear and ageing. I personally use: DriveX
