Are failure of Clipboard History and Windows Stickies linked?

A while back I started a thread about the failure of Clipboard History, for which I have still not found a fix. I have just discovered, after neglecting Stickies for a while, that it has also failed. The loss of both of these services is a bind, as with them I lost some passwords (including the one for this site) and other important codes. Fortunately I found Stickies had synced successfully to my Android Tablet, confirming the usefulness of this new feature, but I have not had the same luck with Clipboard History. Recent clips which were stored on a useful third party app, ClipClip, are now no longer listed. I await a reply from the Developer to my question about the possibly of them still hiding somewhere on my PC.

I have re-installed Stickies from the Store and it seems to be working again with current Sticky notes, whereas Clipboard History is still not working at all. The possibility occurred to me that maybe the problems with the two apps is linked? This is probably a silly question, as I do not know of any link between them apart from my use of them for similar purposes. On the other hand I suspect that eventually I will find that both of the problems will be corrected by editing the Registry, something which I have virtually no experience with.

Yes I have tried, without success,the fix at https://www.tenforums.com/tutorials/109799-turn-off-clipboard-history-windows-10-a.html
I thought I had mentioned it but on checking I realise now that I had done that in my earlier thread regarding the failure of Clipboard History.
I do keep my many passwords in a notebook but I like to have some specific ones saved on my devices so that I can copy and paste them rather the having to type them in frequently. Because of this I sometimes do not write them down immediately, relying on them being saved to Clipboard and Stickies, a mistake I will not repeat in future! I have tried a few password vault/safe apps in the past but did not get on with them very well. But I understand that many users do find them very helpful.
