lmHeatmap: node stack overflow

[f6v]

I'm trying to run the example with the simulated data, and I've got a failure on the following line:

lmHeatmap(scAI_outs, color.by = "labels")

Error in is.leaf(dend) : node stack overflow Error during wrapup: node stack overflow Error: no more error handlers available (recursive errors?); invoking 'abort' restart

Quick search led me to trying the following: options(expression = 1000000), though the result was the same. Have you seen this issue before?

I'm running R 4.0.2 on macOS.

Thanks in advance!
