STEPS TO REPRODUCE
(unclear: this happens every time I try to export this particular project, but I have not tried to reproduce the issue with other projects)

OBSERVED RESULT

The aforementioned error, no file is output

EXPECTED RESULT

The film is rendered

SOFTWARE/OS VERSIONS
Windows: Windows 11 Home (version 24H2)

ADDITIONAL INFORMATION

I have tried rendering only a portion of the film, and I still get the above error (even though the portion of the film doesn't contain most of the files mentioned).  I have tried rendering in different formats and also get the error.

The files all exist at the locations described in the error message, and the program has access to those files.  Some files contain characters like ß or ä — could this be culprit?  Only some files have that issue, though — most of the files referenced in the error message do not have this problem.
