Windows 10 Matlab suddenly won't open

While I was working on Matlab, my computer crashed (it does this every now and again, it's an old windows HP laptop), but when I rebooted the laptop, the current version of Matlab won't open up: I click on the icon, it briefly flashes and then nothing happens. The previous versions still works fine, so it's not urgent, but obviously I'd want to be able to keep working on the current version.
Thanks!

I had this problem on mac and after I ran the activation again it opened fine after. Be sure to allow access to documents

I had the same problem. Deleting my preferences folder did the trick, as described in the solution here:https://www.mathworks.com/matlabcentral/answers/97167-why-will-matlab-not-start-up-properly-on-my-windows-based-system

Thanks for your comment. I solved the same issue by renaming the preference.

I suggest that install a last update on your installed matlab version:
For example 2018a:
I tried this and fixed it.
