Hi,
For information how to fix time step too small errors, view the knowledge base from the link shown below:

I got your circuit to work by changing the follow:
Tmax from 1e-5 to 1e-3 sec
Reltol from 0.001 to 0.01
Rshunt from 1e+12 to 1E+7
And Integration method from Trapezoidal to Gear.

Multisim calculates RMS in two ways:
1. It removes the DC offset and from the signal and then calculate the RMS value, instruments uses this method.
2. The other method is to leave DC off set vale and then calculate the RMS value, probe uses this method.
In this example, I have an AC source with a 1V DC offset, from the result you can see the probe RMS value being higher than the meter reading due to the 1
