Dex File Error when running Android Studio Application

Question

I tried running my android studio application, but I got the following error:

AGPBI: {"kind":"error","text":"Cannot fit requested classes in a single dex file (# methods: 77644 > 65536)","sources":[{}],"tool":"D8"}
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: 
The number of method references in a .dex file cannot exceed 64K.

This has never happened before when I tried to run the application, but suddenly it started happening. It seems like it's something to do with a dex file, but I have no idea what that is.

I would appreciate any sort of help on this matter. Thanks!
