1.5.4 Macbook freeze and restart when I encrypt larger file

Hi. I’m facing an issue while using Cryptomator on my MacBook Pro (10.15.4). When I was copying some larger file to my vault (3gb in this case), my laptop will freeze and restart after 1-2 minutes of freezing. However, I was able to copy smaller file (<500mb) to the vault without any issue. Can anyone please help to assist on this problem?
Thank you in advance.
