FlowDroid repeatedly keeps on printing "Constructing callgraph... " Analysis is not terminating for hours!

Hello @StevenArzt! Whichever apks I analyzed to generate a call graph, FlowDroid repeatedly keeps on printing "Constructing callgraph... " Some partial running logs of an apk is as follows:

[main] INFO soot.jimple.infoflow.android.callbacks.DefaultCallbackAnalyzer - Running incremental callback analysis for 14 components...
[main] INFO soot.jimple.infoflow.android.callbacks.DefaultCallbackAnalyzer - Incremental callback analysis done.

Does it mean that the generated call graph is not completed? How long should one run the analysis to get final call graph constructed? (Because it wont terminate for 45 minutes for some small apks like Slack, Twitter, Instagram etc.)

I am using: java version "18.0.1.1" 2022-04-22 Java(TM) SE Runtime Environment (build 18.0.1.1+2-6) Java HotSpot(TM) 64-Bit Server VM (build 18.0.1.1+2-6, mixed mode, sharing)

Could you please suggest ways to resolve this issue? Thanks.
