SketchUp crashes when importing .DAT file - Importing shortcuts

Hello everyone ! When I am trying to import the shortcuts (keyboard buttons in order to work faster) that were done by a colleague, my file crashes and I am not able to use the same shortcut commands as him. It is a .DAT file. Anybody knows how to solve this issue please ? I would be super grateful

First I thought my file might be too heavy but I have tried to do with an empty file and it still gives the same message of crash. I am attaching screenshot how I am trying to import it, after which it asks me if I want to save the settings over my old shortcuts, and then at the end it gives me the error crush message. Thank you in advance for your help !
