Why is my S10 crashing to shutdown

After experiencing the Google update error with “Android system webview" I can not update or reinstall as my phone shuts down. However it gets to the Sprint logo and freezes. It remains here until losing power.

After total power loss I recharge battery about 15% and restart phone. I try going to store to update my web view and crash phone into shut down. I try to access through settings/applications and again phone crashes to sut down. Sprint store no help.

HELP me please.
