Error in 'projectData'

[Yujj1123]

Hello,
thank you for developing this package. I have encountered problems when applying. I hope to get your guidance. When I run
cellchat <- projectData(cellchat, PPI.human)
I receive the following error:

Error in isTRUE(r <- .Call(Dim_validate, object, "Matrix")) :
object 'Dim_validate' not found

I don't know the reason for this error. I'm looking forward to your reply!

Do you have this issue when running the example dataset?

Thanks for your attention！My problem is caused by Matrix1.6 incompatibility. After changing Matrix to 1.5-4.1, CellChat now can be run properly.
