After trying A to Z, it seems that the problem isn't on our end. It's also not a problem on Google's end. The App built used for connecting GBP to our Squarespace website under Location Management is not a Verified Google App. For the permissions to go through, and link the GBP to the Squarespace website, it needs to be a Verified Google App. Whether they did not request it to be verified with Google or Google did not allow it because it does not meet their guidelines to be Verified, Squarespace needs to fix this ASAP. I have raised this issue to the support team so hopefully this problem will be fixed soon. It wouldn't hurt for others to submit a ticket with this issue to Squarespace support to raise awareness on the problem. In case anyone is wondering how I came to this conclusion: I saw in my Google Admin that manages my Domain/Squarespace Website under App Access Control that the other Squarespace Apps (Squarespace & Squarespace Analytics Search Console) were listed as "Google verified". The app "Squarespace Business" that is used for Location management was listed as "Not Google verified". These are all considered Third party apps for Google, and need to be verified to allow access/permissions to Squarespace.
