Purple edge on white objects

Hi, complete amateur here.
Just bought a Sony a6400 and first time shooting in S-Log 3. There's this weird purple halation on the edge of the white parts of my shot that I can't get rid of.
Is this because I overexposed my shot, and is there a way to fix this in Davinci resolve? Thank you very much
