Hi,
I am new to LTspice, but I recently simulated a simple circuit with the new version of LTspice 24.0.12 and I got quite different result with the previous XVII.
I tried to perform .AC simulation with the 24.0.12 and I got below pic, the gain is going up from around 20khz.

It is not the same with the simulating of XVII, here I also attach the pic of XVII . With the same schematic, the gain is going down from around 20khz in XVII.

I have no idea why this happen. Could anyone help me? Appreciate for it.
Here is the .asc file .InvertingAmplifierCircuit.asc
