transmission_depth program turns off

[starcolor_a]

When using the transmission_depth alone, the program works normally,

If you use transmission_depth and another transparent material at the same time, the program turns off.

The program will be turned off unconditionally when used at the same time without overlapping. How can I solve this problem?
