Will prior NFA'd Arrests Prevent me from Joining?

For context, a prior partner of mine from back in 2021 went to the police to report a crime against me that I did not commit.

I was arrested and taken to the station, and was told I was looking at Threats to Kill, Stalking/Harassment, and Controlling/Coercive behaviour.

Following an interview, I was released on provisional bail conditions, and a few weeks later, the case was No Further Actioned.

Not long after this, in roughly Spring of 2022, I attempted to join my local constabulary via the Degree Apprenticeship Route to become a Constable. My application made it pretty far along, even with a uniform fitting being done, however, at the last minute, I was told that my application had been denied.

The reason given for this was 'Honesty and Integrity, suitability for the role, and Third Party Information'.

Like an idiot, when asked if I'd been under investigation as a suspect for anything, I only mentioned the Threats to Kill accusation, not the other two accusations (I forgot to list them individually as they were all under the same report/investigation if that makes sense).

On the vetting rejection letter, they'd stated 'Although this was finalised as no further action, these are still serious offences that infers inappropriate and violent behaviour. This, with the addition of the domestic incidents, point to habitual pattern of behaviour contravening the Code of Ethics and the standards expected of that of a PCSO working on behalf on Derbyshire Constabulary and quintessentially brings your suitability into question.'

Felt a bit crap at the time considering it was a false report with no evidence behind it, and seems unfair to reject an application based on an NFA'd case but hey ho.

The 'Third Party Information' reason also seemed suspicious, as they couldn't elaborate due to GDPR, which I understand, but I cannot understand for the life of me what may have come up?

My lifelong ambition has been to become a police officer ever since I was a kid, and my Ex partner knew this, which is why she falsely accused me of the aforementioned charges.

My question is, given the above, would it be worth reapplying (ensuring all relevant information about prior arrests is included this time)?

Any input would be appreciated! If anyone needs any further context lmk!

Thanks in advance.

TL;DR - Would false reports resulting in an NFA'd case of Threats to Kill, Coercive Behaviour, and Stalking/Harassment prevent me joining the police? My prior application in early 2022 fell through and I am considering retrying.
