    posted a message on New Release Crashes All Singeplayer Worlds - NO MODS! Please Help!

    I woke up today and realized that all of my singleplayer vanilla worlds crash upon being loaded up. I have NO mods and never have modded Minecraft. The worlds have worked fine up until today and I have tried reinstalling both Java and Minecraft to no avail


    Here is my crash report from one of the worlds:

    ---- Minecraft Crash Report -------- Minecraft Crash Report ----// Everything's going to plan. No, really, that was supposed to happen.
    Time: 1/3/18 2:17 PMDescription: Exception in server tick loop
    java.lang.ClassCastException: aom cannot be cast to aps at bcb$c.a(SourceFile:1844) at bby.a(SourceFile:42) at bbu.a(SourceFile:95) at aze.b(SourceFile:437) at axw.a(SourceFile:803) at axw.a(SourceFile:791) at on.c(SourceFile:115) at net.minecraft.server.MinecraftServer.l(SourceFile:328) at chd.a(SourceFile:114) at chd.j(SourceFile:130) at net.minecraft.server.MinecraftServer.run(SourceFile:434) at java.lang.Thread.run(Thread.java:745)

    A detailed walkthrough of the error, its code path and all known details is as follows:---------------------------------------------------------------------------------------
    -- System Details --Details: Minecraft Version: 1.12.2 Operating System: Windows 7 (amd64) version 6.1 Java Version: 1.8.0_25, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 119115032 bytes (113 MB) / 218103808 bytes (208 MB) up to 1073741824 bytes (1024 MB) JVM Flags: 8 total; -XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx1G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=16M IntCache: cache: 1, tcache: 1, allocated: 12, tallocated: 94 Profiler Position: N/A (disabled) Player Count: 0 / 8; [] Type: Integrated Server (map_client.txt) Is Modded: Probably not. Jar signature remains and both client + server brands are untouched.


    I cannot even load previous versions (backups) of my world that were backed up from a time when the worlds actually worked without the worlds crashing


    I would greatly appreciate any and all attempts at help!
