For me it looks like this:

Did you install the help in the same folder as the program?
And did you ensure the Help version exactly matches the installed LO version?

Pop!_Shop distro manager does not show LibreOffice Help
Quite possible the offline help was not installed at all.
Permissions are blocking my attempt to unpack DEB Help file, from the wild.
Re-install of LibreOffice suite with all apps, also fails to install Help.
Therefore, I uninstalled all LibreOffice apps, waiting proper procedure
This issue was re-solved after PopOS support assisted with OS refresh, and a browser security conflict was corrected.

Browser Security Issue
Any browser installed as a Flatpak will be sandboxed without read access to local file system or local LibreOffice help files [F1] key.
CR
This is my preferred behavior for online browsing & email (Evolution), so now Chromium remains my Flatpak browser install, and is selected in my Debian gnome system settings as default browser.
CR
However, the only way LibreOffice local [F1] HTML help files are accessible is if a browser can read them. Therefore, Firefox --preferred for PDF rendering-- was installed as a .deb package along with LibreOffice, with full access to local help files [F1], rather than sand-boxed as Flatpak’s.
CR
Firefox must also be selected for local HTML file association, and when LibreOffice help asks which browser to open. The extra settings are worthwhile to me for keeping the sandbox security of a FlatPak browser.

Anyone who is over 50 yrs of age should know by now, not getting ripped off is a full time job, and rip-off artists peddling stolen ID’s & cypto investment products, are integrated into the banking and economic system. The more security becomes a priority in your phone or computer habits the safer you become.
CR
OS Refresh
The OS refresh, from updated distro image files, was planned ahead of time with PopOS distro support, who walked me thru it on the phone, with the same Technician who tried to resolve LibreOffice F1 issue by other means.
CR
I wanted the OS refresh for security reasons also, since some of my applications were downloaded in the wild, not vetted thru my distro app channel --the Pop Shop–, nor checked manually for encryption keys after install. This bad security practice opens any computer to insecure malware, so I wanted a fresh start anyway to remove some less secure software from the wild.
CR
Any OS refresh requires some user competence to make complete backups of application data, and the ability to re-install & re-set apps, along with common system settings.
CR
Now I keep some read.me notes of configuration changes to the Debian Linux .bashrc in my backup directly. The .bashrc and .profile are similar to (Windows config.sys and autoexec.bat) files, which I grew up with in my early days of computer use.

Update on using FlatPak browser installation to sandbox online malware in the wild.
cr
Browser FlatPak can’t sandbox web or malware when using browser “Save As” to local disk. CLAM virus scanner is finding malware trojans in my browser files saved to disk locally.
cr
Suggestion: 1) Save to PDF
PDF preserves format, but only converts sophisticated-image malware to a different format, where malware activity depends on local file systems to restrict PDF file activity / permissions
cr
If saving as PDF is not possible from browser, select text on screen, copy, then paste into a word processor for Export to PDF.
cr
Example: 2) Save As *.txt
Saving as plain TEXT strips out all format, images, and browser malware from the wild.
cr
If browser can’t “Save As” TEXT to strip out all malware embedded in tiny files or images, web page text must be copied & saved to separate editors.
cr
Apple’s Safari browser has a reader page view, which can be emailed, so messages can be saved as text, or copy/pasted to local text file.
