I can disalbe all the offending plugsins - I know which ones are failing. The pivotal one is KeeChallenge and the database won't open without it. I can dump KeeChallenge - and my Yubikey investment - but that's not the point. I committed to KeePass years ago because it works with Yubikey.

In my case Win10 Pro x64. v1909 fully updated. It is not just a KeePass issue - it's a KeePass plus specific plugins issue.

Just an update on this issue. I have experimented with multiple further Win10 updates and re-loading of the current KeePass version - and it continues to fail to load wth the KeeChallenge plugin and multiple other plugins. As suggested, KeePass v2.38 does indeed work successfully with all the plugins - just as the latest version of KeePass used to before the Win10 updates. So - thanks for the suggestion - I will have to hope that some subsequent update to KeePass or Win10 will allow them to play...

Thanks for the response - and the PNG advice. I can restore / rollback Windows - but Win10 will keep trying to (re)update relentlessly... :( Rolling back KeePass is a possibilty. Can I ask what suggests KeePass 2.38 might work with the latest Windows updates when 2.43 doesn't? Thanks David.

I use KeePass with a number of Plugins including KeeChallenge (for Yubikey authentication) and QuickSearch. All works fine for years - until some days ago when loading KeePass produces error dialogues about Plugin incompatability (see attached PDF file examples). Most importantly this prevents me from opening my database - because it is KeeChallenge protected and I can't run that plugin. I do have the fallback of opening my database using the secret key - but this renders the Yubikey authentication...
