Sculpting in blender is a stepped process where to many vert in a model result in more resource being require to move the surface around which can cause crash.
By keeping the model to a decent ''resolution'' or vert count if you prefer. You start to build up the shape.
It essentially like stilll pretty close to drawing you start with big shape(2d or 3d) one depending on a case by case basis and once you need more detail well you change the resolution( or voxel size in other word) so that you have more ''data'' to move around. That step is called ''remeshing'' and it can be pretty invisible to a new blender user because it '''hidden'' around so much the other menu option and is only available in sculpting mode soit can take some time to be found when you don't even know it existence.
There also something called dynotopo i am not super knowledgable on that specific tool but it basically like changing the resolution of the surface but base on the brush rather than assigning the resolution to an object i believe you cannot use both dynotopo and remesh as remesh will recalculate all vert in an object will dynotopo is more like localized resolution. So one is like i would say good for like small sculpting(dynatopo) and one is more like for whole object being sculpted.It possible to remesh as many time as you want but note that by doing so some of the surface can change which can tend to smooth detail that why in sculpting you want a restructure stepped approch so that you can maintain the level of detail without slowing down the machine to early in the process which can cause lag for the whole project.
The problem is that whatever you do if you don't understand how to caliberate the value that determine how much resource your eating your running yourself into the wall.
But it also a good thing to play around and figure out what are your machine limit by testing at what vert count you start to run into lag.You can activate what call statistic which can help you see the information of an object such as the vert count which is basically your unit that tell you if you have a low or high probability of crash.
My guess is you were using dynotopo and got the vert count to high because you had the resolution set to high or you simple remeshed but you took a value that was to heavy for your pc.
