You can first try to roll back your version with a system image backup taken before you started to notice the issue, because it seems that for some reason, there is some corruption on your system. Or you can use UUPDump ISO from the following link:
UUP Dump – Get Insider Fast Ring ISO – Win10.Guru
or preferably here is the skinny and fastest way:
Windows Insider - Get Latest Fast Ring ISO image
Mount the .iso created by UUPDump procedure and run setup.exe file. Don't let it check for Updates; That can be done after your install is up and running fine.
