[Crash] Only DragonAPI and Forge things

[Fabric Of Nothing]

Firstly, hello!
I usually use MultiMC for mods, but for some reason I like using offical Minecraft Launcher more and my favourite mods are usually intalled for offical launcher. After playing some with Rotarycraft, I decided to install it to offical launcher. But DragonAPI caused a crash during starting. I deleted everything with exception of shaders, resourcepacks etc. Only installed forge andDragonAPI but keeps crashing. Here's the crash log:

Thanks for reply, it's my fault I forgot to say it was a new downloaded file. This annoying crash log made me download same file 3 times. It is working fine if I use MultiMC but offical launcher thinks it has problems.

 

[RavynousHunter]

Does the mod file have ".zip" at the end? If so, try removing that extension, since I know it can cause issues.

 

[Reika]

I am not familiar with how launchers work, so I cannot tell you why one launcher is voiding the file, or preventing it from being accessible.

 

[Fabric Of Nothing]

Mod isn't a zip file. It is jar file like all other working mods.
It seems like I'll have to use MultiMC. RIP offical launcher.
