After months of use, uVision 5 is crashing on startup. Everything shut down OK with previous use. Using Visual Studio debugger, looks like Unhandled exception at 0x00000000 in UV4.exe: 0xC00000005: Access violation.
Problem fixed by clicking the .uvproj to open Keil vs. using the shortcut. Now the shortcut works as well.
Had the same issue just clicking on the uv4 icon on the desktop you would have this happening but as suggested going to the project folder and selecting the project file the ide would work as expected
