I have the same issue,
When I launch the game through steam I get the easy anti cheat splash screen then the error saying
"there is a problem with your games setup please reinstall your game”
made sure direct X was up to date,
reinstalled easy anticheat
ran in administrator
verified the game install on steam twice
I have redownloaded the entire install and the problem remains.
Worth noting that it appears to load the easy anti cheat splash screen twice!
