Issue comments
You might fix the bug by reducing the amount of RAM by doing as suggested in the linked issue, but if this does not help, you can't do much.
Minecraft decompilation requires a lot of RAM and the required amount get bigger with each Minecraft update.
You will have to update computer which should be done in any case because 32-bit technology is very outdated. Most likely, you have 64-bit compatible processor but for unknown reason 32 bit OS. In such case, consider installing 64-bit Windows which is wise in all aspects, not only for MCreator.
You did not assign enough RAM to MCreator. Add more RAM to MCreator from the preferences menu.
If you are using the 32-bit version, consider using 64-bit version instead as you will have a hard time with only 4GB of RAM and using MCreator. This is also noted in the recommended specifications so this issue is closed as works as designed.
On 64-bit computers, you should always use the 64-bit version. Check this issue for more details: https://mcreator.net/tracker/issue/40598
