I've recently upgraded to Seurat 5 and I'm now receiving the above error when trying to run CreateSeuratObject() on a script that perviously ran without error. This script downloads publicly available data from a repository and runs the basic Seurat process. It worked previously when using Seurat versions 3 and 4.
However, this error also arises when running CreateSeuratObject() using the gene expression matrix and meta data extracted from the pbmc3k dataset:
library(Seurat)
library(SeuratData)
BiocManager::version()
#> [1] '3.18'
unloadNamespace('Azimuth', 'TFBSTools')
InstallData("pbmc3k")
data("pbmc3k")

I have seen other posts recently on this issue and have tried to implement the following suggested 'solutions':
Upgraded Bioconductor manager to 3.18 (and updated packages accordingly)
Tried removing the Azimuth and TFBSTools packages using unloadNamespace()
I appreciate this may be an ongoing issue, but thought I'd start a new thread as the other threads imply this has been resolved.
Any help you could offer would be greatly appreciated.
