It Likely Wasn't Supported For The Game Since It Launched Well Before PS5. I'd Recommend Saving Yourself The Headache By Downloading X360ce A Free Program That Emulates Your PS5 Controller As An Xbox Controller. I Have Used It Allot Over The Years And It's A Life Saver At Times. Once You've Created And Mapped Your Controls To Your Liking Remember To Save Your Profile. You Need To Leave The Program Open In Your Taskbar With Your Profile Active Before Launching A Game For It To Work. Hope It Helps
