Hi,
SSL_CERT_DIR in the git push log is a side effect from a regression in 14.5.0. This is discussed in SSL_CERT_DIR info message on git pull/push after update to 14.5 and tracked in this issue with a workaround.
The issue linked by @twk3 has a workaround with a binary too, thanks @stanhu 
Since you were not able to downgrade, maybe look into applying the workarounds and let the patch release upgrade override the files later.
Cheers,
Michael
