Can Confirm (same crash log's as above)

I believe this crash is a direct result of the change made in forge version ".43", when comparing the Stack trace report to the change log.

Forge Change Log

~ snip

• 40.1.43 [1.18] Avoid exclusive synchronisation in block render type lookups (#8476)
  ~snip

Again can confirm Peca21's report that when using versions below Forge ".43" there is no crash however as soon as you use any version higher (".44" being the next version publicaly valiable after ".43") the crash occures.
I have tested forge versions from ".31" right up to ".47"

.41 forge works fine, .44 crashes, I can't test 42 and 43 since curseforge doesn't have these versions.
But it looks like the problem is in 43

MinecraftForge/MinecraftForge@194f110
MinecraftForge/MinecraftForge#8476
MinecraftForge/MinecraftForge#8664

It should work once MinecraftForge/MinecraftForge#8671 is merged.

Forge is planning to revert this change. Until then, use version 40.1.42.

Still crashing in Forge .51

This is long since fixed.
