[Bug] Perl error in QuickTime.pm

[tipa]

I use ExifTool in my app and this error happened on a users device - I wasn't able to reproduce it myself and I cannot provide any test image/video to reproduce this with. I don't even know what kind of file it happened with.
Below the required information as requested here

1) System type (Windows XP, Linux, Mac, etc)
Windows 11 10.0.22631

2) The ExifTool version you are using (the output of the "exiftool -ver" command).
13.19

3) The specific command line you are using (or a sample script if having problems with the API).
Unfortunately I don't know the exact command being used, but I can do some more research/logging to get this information

4) The console output from the command.

Can't use string ("") as a HASH ref while "strict refs" in use at C:\path\to\exiftool\exiftool_files/lib/Image/ExifTool/QuickTime.pm line 9882.
I believe in the latest version 13.20 the problematic line in QuickTime.pm is now 9894

Thanks.  Pity you just missed getting a patch into 13.20.  This will be patched in 13.21.
