This tutorial shows you how to test a lavaan bifactor model in R, that is a model with
a general factor and several group factors. With the R package lavaan bifactor cfa can greatly enhance our understanding of construct-relevant multidimensionality.

Bornovalova, M. A., Choate, A. M., Fatimah, H., Petersen, K. J., & Wiernik, B. M. (2020). Appropriate use of bifactor analysis in psychopathology research: Appreciating benefits and limitations. Biological Psychiatry, 88(1), 18-27.
Webpage with strategies how to deal with convergence problems in a bifactor model (the answer there is from one of the authors of the journal article mentioned above, B. M: Wiernik):
