Would changing my language make a difference?

I am currently in the process of learning to become a programmer and looking for work as well as i currently have zero working experience. My programming logic is really bad at the moment and i have been trying to build it. Java has been my main language for a while and its through java i learned the fundamentals of programming. However, and i’ve heard this sentiment from others too that, java might be holding me back a little or at least making my experience not so good. While i don’t dislike using it, i just feel like i keep trying everyday to polish my skills but i end up learning nothing. Its become a routine now for me to open up leetcode and hackerrank and trying solving the problems(mostly easy ones) and i end up having to look them up after giving each problem like an hour and a half. I am most likely the one at fault here as it would imply my fundamentals are not correct and the language isn’t to blame which i would totally agree with. But i have gone through those fundamentals probably like 20 times and yet it still isn’t helping me. So thus why i wanted to ask will changing my language make even a slight difference? Kotlin was the one that many recommended to me as its supposed to be similar to java but have more features and is easier to read and write. Mind you i don’t plan on ever quitting java for good. I still like it, i just feel trying to out something else as everything i possibly could do with it i have done with my current set of skills and i need to do something else now to further progress my programming career.
