I finally made this problem go away for an extended time. I tried all of the cleaning methods and they worked temporarily. What worked for much longer had to do with making the best puncture hole in the bottom of the k cup. The hole needs to be au shaped hole with a flat side. The silicone boot needs to be good to push the kcup back off the needle. I replaced the needle assembly and then I started pushing the kcup all the way down with my hand before closing latch. The plastic that is supposed to push the cup down flexes too much after it’s aged and it doesn’t push the cup down well enough. Doing this and doing a cleaning with straight vinegar has kept the problem away for several months. Good Luck!
