Hi and thank you for your question.
The first thing that comes to mind is there is a problem with your clutch interlock switch. I suggest looking at the bottom of the bracket where the clutch lever mounts and find the switch. Trace it down into the headlight and check the connections, making sure they are not unplugged. If that is ok, disconnect them and use an ohm meter to check continuity between the two wires. You should show continuity/no continuity as you pull the lever in and release it. If it isn't changing, the switch is not functioning properly.
The next thing would be the side stand switch. The easiest way to check that is put the bike in neutral and see if it starts, providing you have already confirmed the clutch switch is functional. I am guessing you have tried this but wanted to throw it out there just in case.
As far as checking fuses, never trust your eyes. Always check for volts to both ends of the fuse or check continuity across them. There could be an open that is not visible. A test light is the easiest way to check them, and when I do, I hit them all just in case there is some minuscule chance a seemingly unrelated circuit blew a fuse and is killing the one I am working on.
Let me know how that works out for you and if we need to dig deeper, we will
