When i send a test email it tells me it has a ssl certificate issue

My website is home hosted on wamp apache 2.4.51 and I have added SSL with certbot this is what I put in the vhost config

SSLEngine on
SSLCertificateKeyFile "C:\Certbot\live\crosskartcanada.ca/privkey.pem"
SSLCertificateFile "C:\Certbot\live\crosskartcanada.ca/fullchain.pem"
SSLCertificateChainFile "C:\Certbot\live\crosskartcanada.ca/fullchain.pem"

and everything works fine except for the emails, when I try sending a test email I get this error

Versions:
WordPress: 5.9.2
WordPress MS: No
PHP: 7.4.26
WP Mail SMTP: 3.3.0

Params:
Mailer: sendinblue
Constants: No
API Key: Yes

Debug:
Email Source: WP Mail SMTP
Mailer: Sendinblue
[0] cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

I have a feeling this has something to do with certbot because it makes the certificate in a .pem file but i have no idea how to fix this
