27M with no sexual/romantic contact for 2 years...what am I doing wrong?

I'm posting this in the hopes of receiving some genuine advice. Whenever I have tried to speak to friends about this the response is often 'I don't know' - which suggests there's something they're either not seeing, or don't want to say out loud.

I think it's worth noting that I was a bit of a later bloomer compared with fellow friends as a teenager when it came to my dating/love life. I didn't lose my virginity until around 19. Once I 'broke the duck', however, I was pretty in the flow. Between 19 and 25 I had a pretty steady flow of relationships of varying lengths, and made connections with multiple other women as well - even during the pandemic. I would say I was doing pretty well without reallt trying too much. I don't know what happened but sometime in early 2022 everything just...stopped. No more hookups, no more dates, no more romantic sparks with colleagues or friends of friends...nothing.

My situation right now:

-Job: work in a good job, not the King's ransom but I'm earning quite well for my age. I work from home - and most of my coworkers live hours away, so I don't see them very often.

-Home: I moved home with my parents last year to save money, as I was sick of paying extortionate rent in my area. Now I'd say the money is nearly there to go for a deposit on a house. I obviously now want to leave again, but don't want to pay crazy prices to live on my own.

-Confidence: I'd be lying if my mojo hasn't taken a slight knock with the lack of contact/interest from women, but I'd say I'm a pretty confident guy - I back myself, and Id like to think I'm a pretty well rounded/good looking man.

-Online dating: I have all the apps, and I do use them - however I don't think I'm great at using them. I'm not sure that I like the way they're set up to meet people, or the attitude a lot of people on there seem to have. Still, it's an option, so I persevere.

-Leisure: I go the gym 3x a week so I'm in pretty good health. I'm also a huge football fan so go to the game pretty regularly. My circle of close friends has slightly dwindled with age but I get out most weekends, usually to go for a walk or have a few drinks in town. My hometown is like a pilgrimage site for stag and hen dos, so there's a very crazy/cocaine fuelled undercurrent to the nightlife I try to avoid. Still, it's a decent sized city so plenty of nice bars to go and socialise in. It is worth noting that my current friendship circles are very male-orientated and, despite the girlfriends one or two of them have, I don't meet many other women through them. However, I get out and about enough via these friends to surely encounter someone interested in me.

Yet...my love life is totally on the floor. I know there's some obvious things you could say are holding me back right now - e.g. living at home at my ripe old age, but I've done that for a purpose. Also, this had been happening for a year before that and, surely its not a complete dealbreaker...or is it?

TLDR: I'm racking my brains trying to think of what I'm doing wrong, but I'm struggling to pin it down. All I know is that there's plenty of single women out there looking for a relationship, so this has to be a 'me' issue that I'm failing to resolve. Maybe I'm being blind to an obvious issue that a totally random, unbiased person will be able to pinpoint. So...any thoughts?
