some line suddenly, for no appeared reason compile as commented.
example:

EasyDatapack resembling code:

scoreboard players set @s renew 0
scoreboard players add @s progress 1
grabber = summon marker ~ ~ ~
data modify entity grabber#1 Pos set from entity @s data.Origin
if score @s progress matches 4 at grabber#1 run clone ~5 ~ ~ ~5 ~ ~ 0 -64 0
if score @s progress matches 3 at grabber#1 run clone ~4 ~ ~ ~4 ~ ~ 0 -64 0
if score @s progress matches 2 at grabber#1 run clone ~3 ~ ~ ~3 ~ ~ 0 -64 0
if score @s progress matches 1 at grabber#1 run clone ~2 ~ ~ ~2 ~ ~ 0 -64 0
if score @s progress matches 0 at grabber#1 run clone ~1 ~ ~ ~1 ~ ~ 0 -64 0
kill grabber
clone 0 -64 0 0 -64 0 ~ ~ ~
setblock 0 -64 0 bedrock

Compiled:

Update. I know how to fix the problem, but it is still a strong bug, please make it easier crush while compiling, or compile normally.

if/unless/... ... run (command)

will compile with error, but

if/unless/... ...
(command)

will compile normally
