Start applying after only 4 months?

I was doing ML as data scientist (deep learning in Tensorflow some SQL and basic development in boosting random forest etc) before but with low salary. I got offered SWE job with decent increase in TC so I took it even though I knew there would be almost no ML but more of software development in data engineering. It has been almost 4 months with the new job and I am struggling I think since I am having difficulties with the tickets assigned to me. In my previous job I mostly used Python in Jupyter for model developing and sometimes I wrote Python code for development. The new job requires Java and Scala but also be familiar with things like CI/CD. I want to learn these because I wanted to transition into SWE.

I also feel shy about asking teammates for a help since my level is above average in the team. Should I be asking more help from teammates and try to be open? Maybe ask them to walk me through in some real examples for the projects I am going to be part of?

Or start looking for jobs in ML again? I know programming is still a must even if I want to switch back. After gaining some experience in SWE, I hope to combine all of my skills in data science and SWE to something like Machine learning software engineer.

Note that I am on H1b.

Not with WD anymore this is an old account.
TC: 220k

tl dr: having hard time transitioning to SWE from DS. Want to be ML SWE at some point though. What to do?
