sketchup 23 has nothing to do with your 24 crashing Jermo.
actually, considering your 24 is crashing, it might be better to keep 23 installed too.
you can have both installed and running at the same time, no trouble on that side. most advanced users have several versions on their machines, usually the last 2.
Now, there are 2 sides here. First, to make sure you can work, install su23 by right clicking on the installer and running it as admin. test it, if it’s fine, we can move on to 24.
First of all, when it crashes, do you get a bugsplat ? if so, do you send it ? if you send your bugsplats, @colin can have a look at them and pinpoint your problem.
meanwhile… let’s try some things to diagnose your problem a bit better, let’s rue out common issues
First thing I’d try is to repair 24’s install. Same as above, right click on 24’s installer, then run as admin, and here, choose repair. This should make sure your install is clean, no problem.
from there, did you migrate plugins from 23 to 24 or not yet ?
if you did, try removing them (empty the plugin folder) and see if it solves it. could be a bas plugin.
if not… then it’s not the problem 
You mention it crashes while you adjust previous model, does it crash with a brand new model too ? if a new model doesn’t crash, the problem could be in your existing file you’re trying to use.
If you open a new model, can you very quickly go to preferences / graphics and choose the classic engine ? most crashes in 24 are due to the new engine, DX12, acting up with sketchup and some configs. THe fact that you"re using windows 10 still could indicate your machine is a bit older, and DX12 won’t work well with sketchup. the classic engine is the same as 23, so that should fix it if it’s engine related
since you have a Nvidia GPU, there should be an app named NVIDIA control panel. there, you can choose to use your good GPU on sketchup (you can force it). again, it could help.
There is another app you can download called Geforce Experience. It’s an app from Nvidia to manage your GPU, keep it up to date. again, can’t hurt.
