LO Version:, overheating my macbook pro

Hi there!
I am working on a 30 pages document (no pictures, just text). Sometimes LO Version: arrives up to 94% of battery use. That makes the computer freeze and I have to restart. I do not loss the work, but I would like to see if there is a fix or-if not- would you recommend me to use downgrade this version to a more stable one.
Many thanks!

Try to upgrade to the latest 6.4.2 build. If the problem persists, this might be a case for a report at Bugzilla.

Many thanks! @Gabix
I will upgrade the system. If the problem persists I will mention here the next steps I take to fix it.
