I am now having trouble analyzing my data since I got stuck on selecting the proper statistical test to use.

My data is a 2*3 between-subject design data. The two IVs are one norminal(with values 0 and 1) and one ordinal(with values 0, 1,2), and my dependent variables are interval (rating scale from 1 to 5).

Since my data doesn't follow normal distribution even after log() or ln() transformation and doesn't have homogeneity of variance, I have to use nonparametric methods. Currently I got recommendations of Friedman test and Scheirer-Ray-Hare Test. But I searched online trying to understand them and found that: Friedman is suitable only for one IV with repeated measures; Scheirer-Ray-Hare Test cannot analyze interaction effect.

Would anyone please correct me if my understanding is wrong? And would any method could be applicable for my data? If you could also provide links with examples using package, that would be great. I had a hard time searching for Scheirer-Ray-Hare Test's ready-to-use package.

Thanks in advance.
