In my, limited, experience it looks to me that your layer exposure time is quite high. Try looking around for optimal exposure times for the resin you are using. I'm using an exposure of 1.8 s on a 50 micron layer with satisfactory results (Phrozen water washable model grey resin). I use the Lychee slicer and it has the nice feature of having community evaluated presets for most resins, might be worth checking out. Also a lubricant for the FEP might help mitigate the issue.
