For JetBrains Rider (2024.3.5) on Windows (11) the only thing that worked for me was this Plugin:
In Rider go to Settings (Ctrl + Alt + S) > Plugins > Marketplace > Search 'BrowseWordAtCaret' > Install.
After installing, check if it the plugin is enabled and then go to Settings > Editor > Appearance > scroll down to 'Browse Word at Caret' and check all the options.
(It didn't work without the step above for me)
Then use Ctrl + Alt + Up/Down in the editor to cycle between highlighted usages.
You can change the keymap in Settings > Keymap > Plugins > BrowseWordAtCaret.
