Musescore only starts once

There is something wrong with my copy of MuseScore.

I am using Windows 10 Home Edition on a machine with reasonably capable spec. I had MuseScore 1 until last year I decided to make the switch. I uninstalled MuseScore 1 and I am now using MuseScore 2.0.3. Rev 3c7a69d.There seems to be a problem with the new version though after a few month of usage.

Everytime I start up my Windows and then MuseScore, everything works just fine. I can see on Task Manager that the MuseScore.exe 32 bit process appears under application. When I closes MuseScore, it exits normally and its process is killed off.

However after closing, if I restart MuseScore now, I see that the computer loads a little while and the mouse cursor turns to the wait cursor. Around 10 seconds, the mouse cursor turns back to normal and nothing is started up the screen. I see in the Task Manager that the MuseScore.exe 32 bit process is now under background processes. The process just got stuck there running, using 7-9% CPU power and 36.5MB of memory. Neither the user interface nor splash screen show up. If I start MuseScore once more again, another process gets created just in the same way. No user interface. Even if I "End Task" the processes and restart MuseScore again, same thing happens - No user interface, but just a new background process.

To put in simple words, I can't start MuseScore again after I've opened and closed once. I have to reboot Windows in order to start MuseScore again.

Since I want to get more and more music-related work done everyday, this becomes very inconvenient for me. Can someone help me out? Thank you all in advance. I don't know what other technical information that I can provide to help someone trace/solve my problem. Please guide me if needed.
