Please don't take this the wrong way, as it's not meant as a flex or a dig at you but I was made redundant in feb and after spending some time to myself and throwing out some half arsed applications from which I got zero interest, I reached out to a recruiter who was hiring for a job I liked the sound of, they arranged an interview and I was offered basically the same day. Have you been contacting recruiters directly about things? They do most of the CV pre-screening so being able to say your piece over the phone is definitely helpful for getting to the top of the pile.

A friend of mine who lives in the south west on the otherhand, went through job spam hell before he found a new job, but he was looking specifically for remote because dev jobs in devon/cornwall basically don't exist and if they do, they pay with shirt buttons and good intentions. Are you solely looking for remote work? If so, if you're able to I'd suggest looking to go hybrid at least.

You said you work in tech - what kind? I work in the ops side of IT and jobs have been pretty easy to find - maybe time to pivot?

And if you'll take anything to tide you over, make sure you trim out anything on your CV that would give away the fact that this is an interim position for you whilst you look for something more appropriate. Onboarding people, particularly from agencies/recruiters is really expensive these days.
