this is the final version that im using, seems to work for all situations
read_env() {
local filePath="${1:-.env}"
if [ ! -f "$filePath" ]; then
echo "missing ${filePath}"
exit 1
fi
log "Reading $filePath"
while read -r LINE; do
# Remove leading and trailing whitespaces, and carriage return
CLEANED_LINE=$(echo "$LINE" | awk '{$1=$1};1' | tr -d '\r')
if [[ $CLEANED_LINE != '#'* ]] && [[ $CLEANED_LINE == *'='* ]]; then
export "$CLEANED_LINE"
fi
done < "$filePath"
}

you get any errors?
btw u need to comment or remove this line as you don't have the log function
log "Reading $filePath"
