Have you tried '#!/bin/sh' ?
That's my shebang line.
Have you tried single quotes?
Wouldn't want to. Single quotes alter the behaviour.
Double quotes, single quotes, and no quotes have the same behavior on
my machine:

$ cat debian-user-20200920-1727-gary-dale.sh
#!/bin/sh
doublequote="/root/clamscan-report"
echo $doublequote
singlequote='/root/clamscan-report'
echo $singlequote
noquote='/root/clamscan-report'
echo $noquote

$ /bin/sh -x debian-user-20200920-1727-gary-dale.sh
+ doublequote=/root/clamscan-report
+ echo /root/clamscan-report
/root/clamscan-report
+ singlequote=/root/clamscan-report
+ echo /root/clamscan-report
/root/clamscan-report
+ noquote=/root/clamscan-report

/root/clamscan-report

In the simple case, the quotes are the same, but there are times when
they have different behaviours. I avoid single-quotes so that when I use
them, it's a clue that there is a reason.
Here's what I got with your script:
/root/clamscan-report
/root/clamscan-report
/root/clamscan-report
When I retried my script with the quotes, it started working. I have no
idea what changed from earlier today. I certainly didn't update anything
on either server...
