Preset Syncing

Hello everybody, I activated the preset syncing on mac book pro (mac OS big sur 11.2.2). Since then photoshop is repeatedly on crash for excessive use of memory system.

Going on preferences-general and removing the tick from preset syncing, a confimation window appears but photoshop goes again in crash and I'm not able to conclude the operation.

Could you help me? I've already reinstalled photoshop without success
