I installed biomaRt after the latest R update and I am having problems. Whenever I try to call library("biomaRt") it gives me the following error:

Error in completeSubclasses(classDef2, class1, obj, where) :
trying to get slot "subclasses" from an object of a basic class ("NULL") with no slots
Error: package or namespace load failed for 'biomaRt':
.onLoad failed in loadNamespace() for 'dbplyr', details:
call: setClass(cl, contains = c(prevClass, "VIRTUAL"), where = where)
error: error in the contained classes ("character") for the class "ident"; 
       class definition removed from 'dbplyr'

I tried to re-install it and update dbplyr as well but the problem is not solved. Any suggestions?

I don't think this is really a biomaRt issue, as biomaRt doesn't use the dbplyr package directly. It also seems like this error is somewhat common, and not easy to fix e.g. and

Perhaps start a totally new R session and run BiocManager::valid() which should give an overview of whether you have packages that need to be updated.

If so there will be a section in the output called "create a valid installation with" and some code after that you can copy and paste to update the packages.
