An error produced by IDE on mouse hover on help item after invoke help with `?`

[mig]

Today I observed an error while doing this:

1. Displayed help with command ?mem_used for function in package lobstr
2. Moved mouse over text in help tab with hyperlink (e.g. .Last.value) immediately after command

An error message in console says:
Error in base::args(object) : could not find function "D:/Rlang/R4/R-4.3.0/library/lobstr/help/mem_used"

Does this mean a bug in IDE? Details below

Although help text displayed normally.

Other search here in community was not helpful, neither SO search (at least one found thing is that probably package built version vs my R version 'mismatch' mentioned here ). However, I checked my versions:

• for installed lobstr it is 4.3.0

• RStudio IDE is 2023.06.0 Build 421

UPDATE: installed new IDE 2023.12.0 Build 369, the same error is there.
However, interesting observation: when opening new instance RStudio IDE after previous closed the error temporarily disappears (help hint displayed), but after steps 1) and 2) above error appears again.
