Thank you Sr, that fixed my issue after reboot.
as for Igor answer,
he pointed at other lines that didn't fix my issue, but related; I was looking for this specific line:
# Size for zram based /tmp, total memory / 2 by default
TMP_SIZE=1000M
The description maybe misleading, or doesn't work as expected. After increasing the Zram Swap size, the TMP folder didn't automatically increased to "total memory / 2 by default". I had to change it manually.
Thank you. My issue has been solved.
