Epic Games Launcher won't open without crashing

Epic Games Launcher will no longer open on my PC. I’m running Windows 10 on a Ryzen 7 processor, I have been running the launcher for both fortnite and unreal with no problems until a few hours ago. Now it won’t open and I only receive the following message:

“Multiple Crashes Detected
We have detected that EpicGamesLauncher has recently crashed several times. There could be a number of reasons for this.
Would you like to visit online support?”

I have changed no settings, nor downloaded anything new on my computer. PLEASE HELP - I need my fortnite!
