Game crash "The game crashed whilst exception in server tick loop Error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: This is not a JSON Array."

The world for my modded server crashed and said "The game crashed whilst exception in server tick loop Error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: This is not a JSON Array." when I tried to load it into single player. I assume the problem came when I shut down my PC without closing down the server. I have no clue how to fix so... here's the crash report.
