Open Settings → Apps → Samsung Notes
Click 3 dots on top right
Click Uninstall updates
Try open the Notes again and see if it crash or not. If it doesn't, you can choose stay in this version or try to update Samsung Notes again. Update again may fix the problem itself.
You can backup your Notes by Sync with Samsung Cloud. Or you can backup your Notes by using SmartSwitch.
My suggestion was not uninstall Samsung Notes. It is uninstall the Samsung Notes updates. However, backup your Notes first, then perform uninstall updates.
I do not have 3 dots when I open settings/apps/samsung notes. There is an "uninstall" button at the bottom.but not uninstall updates.
