Run following command, -Xmx4g

kali@Machine:~/BurpSuiteCommunity$ 
java -jar -Xmx4g burpsuite_community.jar

If the burpsuite is not launching try with Sudo, this could happen if you are using WSL on windows.

I am using community edition in above example, please change the jar file as per the version installed in your environment.
