Help not shown when using session watcher

Describe the bug
When using the session watcher, R is not able to find the help files. Without the session watcher, I can see the help fine. Plotting and running View() work fine with the session watcher too as they open in a webview, the problem is with the help only.

To Reproduce
I don't understand what is happening, because some times it works, sometimes it doesn't... but most of the time it doesn’t.

Expected behavior
When running help(function) or ?function, it should show the help on this function in a webview panel, but right now it shows an error (see screenshot) Couldn't show help for path: /library/graphics/html/<function>.default.html

Do you want to fix by self?
I could help if I knew what to do...

My setting.json

// R path for Mac OS X
"r.rterm.mac": "/Library/Frameworks/Python.framework/Versions/3.9/bin/radian",",

// R command line options (i.e: --vanilla)
"r.rterm.option": ["--no-save", "--no restore"],

// An optional encoding to pass to R when executing the file, i.e. 'source(FILE, encoding=ENCODING)'
"r.source.encoding": "UTF-8",

// Keeping focus when running
"r.source.focus": "editor",

// Use active terminal for all commands, rather than creating a new R terminal
"r.alwaysUseActiveTerminal": false,

// Use bracketed paste mode
"r.bracketedPaste": true,

// Enable R session watcher (experimental)
"r.sessionWatcher": true,

My .Rprofile:

options(vsc.plot = FALSE)
options(vsc.browser = "Beside")
options(vsc.viewer = "Beside")
options(vsc.page_viewer = "Beside")
options(vsc.view = "Beside")
options(vsc.helpPanel = "Beside")

Inizia riproducendo help(function) o ?function con r.sessionWatcher abilitato, confrontando la webview della guida con la webview funzionante di View(). Esamina il session watcher e la gestione dei percorsi della webview della guida; il lavoro è completato quando la guida apre in modo coerente la documentazione della funzione richiesta invece di segnalare un percorso mancante.
