Hi,
Yes some time it takes long time for Revit to open in Laptop,But firstly I would like to recommend you check the minimum PC configurations for your Revit Versions in the below link provided.For Example I have gave you Revit 2020 version link
https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles...
And secondly If you are opening a project with Links and worksets I would like you to turn off unwanted links and worksets and then start opening the project .
And also Please check your C drive for space,
Regularly clean your %temp% folder , Recents folder
Hope this should work, And if yes Accept this as solution.
Regards,
