Ive been using samba on windows 10 for years without issues.
Also, if you have installed a firewall on your pi recently, that could be blocking. i think port 445 is for samba. have a google, u can find it out easily.
I would also double check the service status of smbd on your pi via command line, maybe the service cant start?
Maybe check from another device to see if you can access it. Because at the moment you have no idea if the issue is with windows or with your samba service.
Orrrr.....access your pi via Firezilla on windows using SSH to transfer your files.
