Hey team.
Thank you for making such a useful package.

**Attach log files
ArchR has built-in logging capabilities for complex functions. A log file (which will appear in the console output) must be attached to this issue. Drag and drop it here.

Bug Description.
When I use the addDoubletScores function, I get the following error.

> doubScores <- addDoubletScores(
+   input = ArrowFiles,
+   k = 10, #Refers to how many cells near a "pseudo-doublet" to count.
+   knnMethod = "UMAP", #Refers to the embedding to use for nearest neighbor search.
+   LSIMethod = 1
+ )

**How to reproduce
I can reproduce it with the tutorial dataset, and the above code is tutorial's.

Additional Context.
I reinstalled ArchR and ggplot2, and tried to restart R and R studio several times, but the problem wasn't solved.
Could you help me to solve this error?
Thanks in advance!

Hi @yuyuyuto001! Thanks for using ArchR! Lately, it has been very challenging for me to keep up with maintenance of this package and all of my other
responsibilities as a PI. I have not been responding to issue posts and I have not been pushing updates to the software. We are actively searching to hire
a computational biologist to continue to develop and maintain ArchR and related tools. If you know someone who might be a good fit, please let us know!
In the meantime, your issue will likely go without a reply. Most issues with ArchR right not relate to compatibility. Try reverting to R 4.1 and Bioconductor 3.15.
Newer versions of Seurat and Matrix also are causing issues. Sorry for not being able to provide active support for this package at this time.

For me, downgrading specifically ggplot fixed this. This worked for me:
conda install conda-forge::r-ggplot2=3.3
I think its an error with ggplot2 3.5.0

[EllenvdL]

@juliabelk For me downgrading ggplot2 does not fix the problem, as I get the following error:

Error: package or namespace load failed for ‘Seurat’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 namespace ‘ggplot2’ 3.3.0 is already loaded, but >= 3.4.0 is required

Do you also have a different version of Seurat?
