Could you please share us how did you create the dynamic hyperlinks?
What's the version of Office are you using now? Have you updated your Office or Windows system before this issue appeared?
Currently, please right-click the the text of "object does not exist", check whether threre is the option of "Linked WorkSheet Object" and "Links" button.
If yes, I suggest you take a screenshot for Links windows as follwoing.
Besides, please provide the correcr path of the linked file. (If there is any privacy information, you could cover it on image, or use symbol "X“ to replace it when you paste characters here.)
If your want to refresh your links, I suggest you press "F9" key instead of "Update Link" to have a check.
Any updates, welcome to post back.
