I have tried almost everything on every forum to fix this issue but my steam application just keeps jumping up and down without opening ever since I updated to Mojave. Please advice as to how I could fix this issue?
MacBook Pro (Retina, 13-inch, Mid 2014), macOS Mojave (10.14)
If you have the latest https://store.steampowered.com/about/ , then you will have to wait for update to their app.
or contact their Support: Steam Support
You can always fall back to High Sierra if it is mission critical.

I had this problem too. None of my 32 bit apps will run. This seems to be an uncommon problem - many people seem to be able to run Steam.
I found a solution that seems to work. I posted a thread in this community that explains what I did. The thread is called:
32 bit applications with Mojave
Don't bother updating Steam - the latest version is still 32 bit.
Steam application does not open on Mac after Mojave update
