ERROR. Game crashed.

Whenever I press "PLAY" in minecraft java edition launcher it closes after "Preparing" and after a few seconds, instead of the actual game, launcher loads in again and I get this error:

" ERROR
Game crashed

An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience.

Exit code: 0"

This is the first part of crash report in case it helps:

1. There is insufficient memory for the Java Runtime Environment to continue.
2. Native memory allocation (mmap) failed to map 234881024 bytes for Failed to commit pages from 262144 of length 57344
   Possible reasons:
3. The system is out of physical RAM or swap space
4. In 32 bit mode, the process size limit was hit
   Possible solutions:
5. Reduce memory load on the system
6. Increase physical memory or swap space
7. Check if swap backing store is full
8. Use 64 bit Java on a 64 bit OS
9. Decrease Java heap size (-Xmx/-Xms)
10. Decrease number of Java threads
11. Decrease Java thread stack sizes (-Xss)
12. Set larger code cache with -XX:ReservedCodeCacheSize=
