We need to see your crash log, which is created after a crash.
On your launcher, click "Launch options", and click the instance you are using. Then, click the small green arrow in the "Game directory" line. In the folder that opens, open the crash-reports folder, then open the most recent text file and copy its content to https://paste.ubuntu.com. Click "Paste!", then share with us the link (the URL) that it takes you to.
