Grouping by expressions of type ARRAY is not allowed
Is there any way can resolve ?

from `test.log`
)

I think you are missing the [SAFE_OFFSET(1)] in your query, This should work
SELECT SPLIT(content_tag, ',') [SAFE_OFFSET(1)] AS tag
FROM `test.log`
GROUP BY tag
Edited for format code.

The legacy SQL query that you have provided will implicitly flatten the array returned from the SPLIT function, which is why it works. Using standard SQL, you need to be more explicit, however:
select tag
from `test.log`,
UNNEST(SPLIT(content_tag, ',')) as tag
group by tag

I am guessing you want something like this:
select tag, count(*)
from (select 'a b c' as tags union all
select 'd c'
) `test.log` cross join
unnest(split(tags, ' ')) tag
group by tag
order by count(*) desc;
This will count the number of tags in the space delimited list of tags.

I am guessing you want something like this:
select tag, count(*)
from (select 'a b c' as tags union all
select 'd c'
) `test.log` cross join
unnest(split(tags, ' ')) tag
group by tag
order by count(*) desc;
This will count the number of tags in the space delimited list of tags.
