How to fix my envelope detector script
A few problems, one of which @Carl has addressed.
Marcus has pointed out the other problem with SPICE netlist nodes:
The SPICE netlist for this schematic would correspond to the schematic above. \$V_{...

How to fix my envelope detector script
To maintain the integrity of the message signal when detecting the envelope, this inequality must be satisfied
$$B < \frac{1}{2\pi RC} \ll f_c \tag1$$
\$B\$ is the bandwidth of your message signal (...

Simulating a basic bridge-rectifier circuit
Despite it's many and serious limitations, even the CircuitLab simulator that's linked here on EE.SE, seems adequate to simulate a full-wave bridge reasonably well. The following schematic:

Simulating a basic bridge-rectifier circuit
There is nothing wrong with the simulation. Here are the same results for LTSpice (notice the differential measurement, \$V_{in}-V_{low}\$):
If you just increase the amplitude of the input signal to ...

Simulating a basic bridge-rectifier circuit
This is what your spice describes - you can see that the voltage source is not connected correctly and does not match your KiCAD schematic:
