New ContributorCritical Warning (169085): No exact pin location assignment(s) for 108 pins of 108 total pins.....
Hello,
Part # 5M1270ZT144.
There are 114 available I/O pins and the design is only using 108 of those pins. The Pin planner shows a separate pin for all of the I/O signals (see image below).
Therefore, why am I getting the following error:
Critical Warning (169085): No exact pin location assignment(s) for 108 pins of 108 total pins. For the list of pins please refer to the I/O Assignment Warnings table in the fitter report.

It's not an error, it's a warning (as it says) and can be safely ignored.
However, you're getting it because you didn't manually set exact pin locations (Location column is all empty from your screenshot). The Fitter picked locations for you that don't get written into the .qsf file as formal assignments unless you back-annotate them. Either back-annotate the Fitter selected locations (Assignments menu) or manually select locations in the Assignment Editor, or better yet, the Pin Planner.
