Read it. The mod requires you to install version 0.4.4+1.20.4 of M.R.U.
- Mod 'Flow' (flow) 2.1.2+1.20.4 requires any version between 1.0.1 (inclusive) and 1.1- (exclusive) of mod 'Mineblock's
Now your other mod is requesting version 1.0.1,in older versions, everything worked fine

I dont support 1.20.4 or 1.20.6 anymore for Sounds.

Update to 1.21 or downgrade to 1.20.1
