I am able to swim breaststroke without issues as I am able to exhale and inhale as much as I want without issues.

However, when I am learning frontcrawl, I realized that I tend to exhale too much and thus I get out of breath super quickly (because I do not inhale enough and then I have to hold my breath).

I know the obvious solution is to exhale less forcefully, but I am unable to do so when doing front crawl. How can I fix this?
