Wd Blue SSD500 keeps crashing/OS won't restart

New SSD500 installed Nov/2020 replaced by WD 04/21. Hv installed the OS 3 times since received replacement. First install was Clone of OS and wouldn’t boot. Next two installs fresh Win10pro.
This morning OS crashed, ran Win10 repair but wouldn’t boot.

First I’d like to figure out what is causing crash and Next how to get a clone to boot. FYI currently running WDHDD OS.

Thanks
