"Sorry! The Quartus Prime software quit unexpectedly."

When I enabled the Input Termination "OCT 100 OHMS" to an SLVS differential input, Quartus error windows pops up during Assembler stage. Synthesis and Fitting are successful. Does anyone encountered this problem? Below are the assignment of the SLVS pins.

set_location_assignment PIN_G15 -to i_CLK

set_location_assignment PIN_G14 -to "i_CLK(n)"

set_location_assignment PIN_G16 -to i_D0

set_location_assignment PIN_G17 -to "i_D0(n)"

set_location_assignment PIN_G12 -to i_D1

set_location_assignment PIN_F12 -to "i_D1(n)"

set_instance_assignment -name IO_STANDARD SLVS -to i_CLK

set_instance_assignment -name IO_STANDARD SLVS -to i_D0

set_instance_assignment -name IO_STANDARD SLVS -to i_D1

set_instance_assignment -name INPUT_TERMINATION "OCT 100 OHMS" -to i_CLK

set_instance_assignment -name INPUT_TERMINATION "OCT 100 OHMS" -to i_D1

set_instance_assignment -name INPUT_TERMINATION "OCT 100 OHMS" -to i_D0

And below is the preview report of the error message.
