Because of MinecraftForge/MinecraftForge#6374 MinecraftForge for 1.14+ does not crash on the first fatal error it comes across and often blames the wrong mod. If you look at your latest log you will see:

Way above the crash that you are linking and that shows in the crash report. Dank Storage 2.3+ or whatever version requires mixin I believe he mentions how to install it on his curse page now but if not go ask him how to fix it.
