Android Studio 3.0.1 won't start up (accidentally reverted something during an update)?

I don't know where to begin with this, but while I was waiting for Android Studio to finish updating, I pushed the ctnl button and the f4 (I know, stupid of me) with the belief that the update would complete faster. However, the update in progress message changed so that it said that the files were then being reverted before completing the process. Now, whenever I try to open up Android Studio, I get this error message:

Internal Error. Please report to https://code.google.com/p/android/issues
