Bug in Skill "Beacon of Hope"

I found a bug in a clerig skill called "Beacon of Hope". The description of skill is: " Advantage on Wisdom and Death Saving Throws. HEALING RESTORE MAXIMUM POSSIBLE HIT POINTS".

I think the bug in that second effect, because when i use the skill, in the hour of dices rolls, the dices disappear and the game stucks, just crash and i can't go on . I tested in 2 situations and i recorded a video to can prove it.

I'll put the link in this post.
