No need. This is pretty clearly a case of memory corruption on the logger.
The clue is

Mar 16 07:04:29 pvweatherbox weewx[7369] DEBUG weewx.drivers.vantage:
Retrieving 513 page(s); starting index= 1
Mar 16 07:04:29 pvweatherbox weewx[7369] DEBUG weewx.drivers.vantage:
DMPAFT complete: page timestamp 2021-02-26 11:30:00 PST (1614367800) less
than final timestamp 2021-03-14 03:00:00 PDT (1615716000)

It asks for 513 pages, then proceeds to get ... nothing.

See the section *Corrupt station memory
<https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station#corrupt-station-memory>*
for
how to clear the logger.
