How to get different mathematical Greek symbols psi and varphi?

Question

How do I change from the first psi and varphi symbols to the second symbols on Overleaf ? Please see the picture. Which package or font will get me the second symbols ?

Edit: on using \usepackage{stix2} I am getting a lot of errors

These were the other packages present in the template beforehand

\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{latexsym}
\usepackage[round]{natbib}
\usepackage{url}
\usepackage{mathtools}
\usepackage{bm}
\usepackage{setspace}
\usepackage{times}
\usepackage{lineno}
\usepackage{graphicx}
\usepackage{xspace}
\usepackage{xcolor}
\usepackage{appendix}

The following are the top three errors

/usr/local/texlive/2020/texmf-dist/tex/latex/mathtools/mathtools.sty, line 241
LaTeX Error:
Command \refeq already defined.
Or name \end... illegal, see p.192 of the manual.
...

l.241 }

@Rmano, please see the edited question, yes I need the package/font. — Guddu, Jun 18 '21 at 08:23
Guessing a font by just the shape is quite complex. If you have a PDF document with the shapes you want, you can analyze it and see if you can find the font name (in unix pdffonts will help). Or you can spend a bit of time (or a lot of it) browsing the LaTeX font catalogue — Rmano, Jun 18 '21 at 08:33
They aren't different symbols, but just different renderings of the same symbols. Nobody should rely on a particular rendering to convey a meaning. — egreg, Jun 18 '21 at 13:19
OK, so the author of the text for the second group of symbols told me, it is one of these three font types - UCP-Maths-Symbol, MinionPro-Regular (OpenType), and STIXGeneral-Regular (TrueType). So how do I get them and use them on Overleaf ? I will appreciate any help. — Guddu, Jun 21 '21 at 22:49
As I suggested above, \usepackage{stix2}... I think that the other fonts you mention are commercial (non-free) — Rmano, Jun 22 '21 at 06:07
I got hundreds of errors when I added \usepackage{stix2} :( — Guddu, Jun 29 '21 at 08:24
no one can debug "I got hundreds of errors" if you get an error post a new question with a small but complete example and show the exact error that you got (usually only the first error is important) — David Carlisle, Jun 30 '21 at 07:36
@DavidCarlisle Please see the top three error messages. Thanks for your help. — Guddu, Jul 10 '21 at 23:06
The times package defines many of the same symbols as stix2; Start by commenting it out. — barbara beeton, Jul 11 '21 at 01:04
