ERROR(ORPSIM-16550)

I got a simple scheme with TPA6211A1 model from https://www.ti.com/lit/zip/slom437. I didn't change this scheme, only inserted voltage marker. And after simulation try I got an error message:

ERROR(ORPSIM-16550): Floating point computation failed during matrix solution. Possible solutions: 1)Ensure that all device parameters are in valid range. 2)Try using .options LIMIT
Overflow, Multiply
INTERNAL ERROR -- Overflow, Multiply
Run aborted
  License check-out time            =       12.47

  Total job time (using Solver 1)   =         .50

INFO(ORPROBE-3188): Simulation aborted

Could you help me? Please, help me solve this problem.

Turn on "Skip initial transient Bias Point calculation" option in simulation setup > transient. Above circuit should work fine with this. 

Analysis directive gets modified as 

*Analysis directives: 
.TRAN  0 3m 0 10u SKIPBP
