So I just popped Dynamic Trees beta 7 into my modpack and went to load it up and got this error right off the bat:

My crash report is right here (and apologies in advance as I have no idea how to do spoilers):

I'll leave that to you. Switching back to Beta 6 solves this.

This was fixed in Dynamic Trees Plus 0.1.0-Beta7.

This is the mod I have in my folder, and launching it gives the error. The only two mod versions for 1.16 on the site are the two betas (6 & 7). Beta6 works. Beta7, that I have in now, does not and gives the error above. I just attempted it again.

Again, switching it so beta6 is in works fine. My only other guess would be something to do with dynamicTrees+ interacting with beta7.

You need to update Dynamic Trees Plus to beta 7.

DT plus beta 6 is incompatible with dynamic trees beta 7.

kk, thank you and thanks for the mod~♪
