Thanks for providing console output. According to it, it seems that you
have two (or more) instances of TeX Live installation, TeX Live
2015/Cygwin and TeX Live 2020/W32TeX.

In your first message, it is reported as follows:

I'm curious whether the latter runs successfully on the command prompt.
Can you test it? (It would be necessary to manipulate PATH environment
variable to give higher priority to TeX Live 2020/W32TeX on the command
prompt.)

And it seems that you are using cygwin bash terminal, not w32 command
prompt. There is possibility that those discrepancy is the source of
trouble. Could you include the output of M-x TeX-submit-bug-report in
your next reply? I'd like to know that your emacs binary is cygwin or
w32-native, in particular.

Ah, sorry. For ELPA installation, the activation must been done in
another way... Well, the revised command line is
runemacs -q -no-site-file --eval "(progn (require 'package) (package-activate 
'auctex))"
(This quotation is for w32 command prompt. I'm not sure it works for
cygwin bash terminal.)
