I feel you on that honestly. Recruiters were mostly useless for me, 90% of the time I got an initial call and then get ghosted after they'd promised to forward my details. I did get a couple interviews but each time didn't get the job. Applying to regular graduate jobs on Indeed and LinkedIn was a complete and utter waste of time, I might as well have been throwing my CV into the void, literally zero responses, same issue as you they were all looking for experience I just didn't have. For me the graduate development programmes were really the only place I got anywhere with my applications, since lacking 'real world' experience didn't just automatically disqualify me like it did the regular 'entry level jobs'.
As someone who a few months ago was also close to just giving up altogether I would urge you to keep trying grad scheme apps a little while longer at least. This is gonna sound like a useless platitude (and of course i've probably got survivorship bias since I somehow got through the whole application process, I'm aware plenty aren't so lucky) but you genuinely never can tell with these things, even if you think the next 10 or 100 applications you do will be more of the same, one of those could be the one where it finally comes together
hope it all works out for you 🙏🙏🙏
