have you deleted your browser history, if not you might be able to find some that way. also do you use your chome sign in on another device if so disconnect it from the internet click on chrome and your bookmarks should still be there
This was also on a previous post, I just copied and pasted it
First thing’s first: Don’t close and reopen Chrome. If Chrome is already closed, leave it closed. Chrome saves a single backup of your bookmarks file, and it overwrites the backup each time you launch Chrome.
Launch Windows Explorer and plug the following location into its address bar, replacing “NAME” with the name of your Windows user account:
C:\Users\NAME\AppData\Local\Google\Chrom... Data\Default
The folder contains two bookmark files – Bookmarks and Bookmarks.bak. Bookmarks.bak is the most recent backup, taken when you last opened your browser.
If you don’t see the .bak file extension and just see two files named Bookmarks, click the Organize menu and select “Folder and search options.”
In the Folder Options window, click over to the View tab and uncheck the “Hide extensions for known file types” option. You’ll now see the previously hidden .bak extension.
To restore the backup, close all open Chrome browser windows. With Chrome closed, delete the Bookmarks file and rename Bookmarks.bak to Bookmarks.
You’ll see your deleted bookmarks when you relaunch Chrome. Any bookmarks you’ve created since you last launched Chrome will be lost.
