PPSSPP stop working

If absolutly nothing changed then the best advice I can give is to atart making sure you are not having the early stages of various hardware failures. Usually if nothing is different then the performance or lack there of should not change. You could have some minor harddrive corruption going on (a harddrive health test might not be a bad thing) along with a general system performance test to make sure nothing else is acting off.
If everything checks out then try redownloading ppsspp and running from a fresh clean copy. If even that does not help then depending on your current circumstances a reinstall of your current OS (after making a back up of important data) and reinstall of all programs you need is a generally good practice to get into once a year or so (less often if you are using a SSD) since it generally keeps windows (to a high degree) and even linux (to a lesser degree) running snappier anyways.
