It is not just the Star Wars universe that utilizes force fields or force shields. They are common in pretty much any movie that involves a fictional space story. Force fields are thought to be possible using plasma. We’ve managed to prove that plasma could catch general problems. But it would need to be superheated and be capable of reaching a superheated temp within milliseconds. Right now, every plasma shield tends to be just one use before plasma has to be replaced too.

The only thing capable of doing it for a long time would be nuclear energy unless we can capture a form of cosmic energy perhaps. Moreover, plasma only stops a small number of things and could not stop things like light. So weaponized lasers would go right through it. Therefore, yes, force fields are somewhat possible today. However, nothing like what you see in the Star Wars universe or most space films.
