I installed LO 24.8.4.2 (X86_64) and its help pack to the same directory. LO Calc and the other modules will not show Help. They are looking for an HTML file (LibreOffice/help/index.html), which does not exist. In Tools-> Options there is no path for Help anymore.
If I directly double-click on “E:\Program Files\LibreOffice\help\en-US\noscript.html” I’m taken to a page in my Brave browser that says “Enable JavaScript in the browser to display LibreOffice Help pages.” That is a privileged page where permissions cannot be configured. I removed NoScript but that did not help.
I tried LO in Safe Mode with the same result.
