SanDisk Secure Access V3 fails to start

I have been using the Sandisch Secure Access V3 for a few years now. Most of the time it works fine but around 1 in 10 times, when I click to open the file it just seems to freeze with this on screen (see attached picture).

I have tried renaming the .exe file, closing it and trying again but the only thing that seems to work is restarting my PC. This can be a pain as it means I have to save and close everything. Do you have any suggestions to fix this without shutting down?

Thanks
