Unable to upgrade to 47 - blank screen + vendor bundle and uncaught syntax error

We got this message:
"Metabase 0.47.7 is available. You're running"

After upgrade to 47.7 the browser returned a blank screen
We tried 47.0 same thing
Had to revert to 46.6.4 - did anyone else get this, and have ideas on how to proceed?

Thanks in advance.

ps. we saw this message but don't know if it is related - and what it means or how to handle it
