I've uninstalled KB4524147 and its saving again, without crashing. So it seems to be a Windows issue and not an Affinity Designer issue. My apologies. Thanks to AlainP for the hint.

Hi @all, first of all, I like to work with your Affinity Designer & would love to be creative with it again. BUT: I've got exactly the same error. When I'm trying to save a file(save & save as), the folder window pops up and as soon as I click the save button, the whole system CRASHES HARDLY and reboots. I can find a corrupt 0 KB-.afdesign-file after booting up again. This only happens in Affinity Designer since yesterday. Other programs are working fine and can save as usual. It worked until the 4th of October! I bought it via Microsoft Store and it worked like a charm before (the last weeks). I'm using Windows 10 x64 (1903) with the latest updates installed(+ all drivers look fine in the device manager). I already reinstalled the latest NVIDIA drivers(gameready and studio were tested). Reinstalled Affinity Designer 1.7.3.481 via Microsoft Store. I couldn't find a fix, yet. So please provide a fix or workaround as soon as possible! Or maybe give a hint, whats causing the trouble with AD, so that I can find a solution to work with it again. But to be honest, without a SAVE function, it wouldn't make any sense to create something with your piece of software. many THX
