Firstly, check you're on the latest version - click 3 dots top-right, hover on "Help" & click "About Google Chrome" - it'll either say you're up-to-date or automatically update it & ask you to restart the browser.
Secondly, have you cleared the browser's cache? Worth trying -
Click 3 dots, hover on "More tools", click "Clear browsing data" (you might have to click that again in the new window) - now, be careful which boxes are ticked. I would only tick "Browsing history" & "Cached images & files", but that's me.
If you're logged in with a Google account, then your bookmarks etc are safe - make sure you know the email address & password you use for that account. If you don't know the procedure for syncing your info, it's here (with more help) -
