Our team got a new laptop, and we tried opening the GRIP file that works perfectly on our old laptop, but this happens. Any fixes?

Unfortunately, you’re out of luck. Some computers simply will not work. Seems to be limited to Windows computers, and the base cause is known (the aliases aren’t being found at runtime).

The next GRIP release will fix this problem, but there’s no timeline yet for when that will be. However, since the fix has already been merged into the master branch, you can build GRIP from source if you have JDK 8 installed by cloning and running gradlew :ui:run from the command line.

My team just ended up creating the file again.
Thanks for the reply though! : )
