"Disable 'Use file transactions for writing databases'" That does not work on my side. "Are you using OneDrive? If so, try storing all files (KeePass application and database) outside of OneDrive." Yes, I'm using OneDrive. I think I checked this already but I will try it again. Also with turn off the transaction function. As I wrote before... On my own Notebook its working without problems now. But there are many colleagues of mine who has still this problem...

I uninstalled KB4515871. I also used the "NetFxRepairTool" from microsoft. For my PC its fine now... no bluescreens so far! I'm using KeePass version 2.43 and the latest .NET Framework now... I don't know why its working now... But on an other PC, its still broken! I removed the latest 2 patches... I was running the "NetFxRepairTool" and I installed KeePass version 2.40, 2.42 and 2.43 and with all versions i get this bluescreens!

I had also the problem with few later versions of KeePass. After removing the latest patch of .NET Framework 3.5 & 4.8, it's working so far! But you have to pause the windwos updates... because everytime windows is searching for new updates, it will install the latest version of .NET Framework again... So its just a solution for the moment.

Same problem here! But I get also a "blue screen" when I create a new password or press save... The longer I open KeePass, the higher is the chance of a crash. I've noticed it since yesterday... maybe it's an effect of the latest windows update? No plug-ins in use. I've used the version 2.43 for a while without any problems.
