Software update failed overnight on TCL Roku TV

My TCL tv model 43s421 sn X00000FH2LX5 running sw 10.0.0 build 4209-93 failed to update overnight. For more than 2 years, most mornings, I watch over the air TV and switch to streaming channels. Today when I switched to streaming, my I noticed my ID and all of the apps were no longer present.
I was directed to setup my tv and update the software.I have gone through this cycle multiple times over the last 6 hours. I have system reset, power reset, move Ethernet cables, and nothing seems to work  

 It is like all the memory had been erased and I can’t restore anything. 

This is hardwired to my internet hub, which still works for my work computer (also hardwired), my tablet, and other devices. The internet connection appears to be okay. 

Any new suggestions?

thanks in advance
