Laplace transfer function generates Fatal error

I’m checking a Laplace transfer function that is a filtered PID version. I isolated the cause: If I remove the denominator of the equation simulation runs smoothly. I have tried rearranging the denominator, but I can’t get the simulation to run. I hope someone can help find a way to solve it.

for .tran, remove uic
but is this really the transfer function you would like to test? bode looks not that common.

Kelvin, thank you for helping again. The high-frequency limited PID version effectively has this form of Bode plot. The PID parameters were taken from an example in the book by Christophe Basso (2012).
