It looks like problem is in encoding. This DICOMs have not UTF-8 encoding, but cp1251. Can support of cp1251 encoding be added? Found another CBCT with UTF-8 encoding - no problem with DICOM viewer:

Comparing the behavior & the error log, this seems to be identical to bug#110 -> https://github.com/ayselafsar/dicomviewer/issues/110

Hi, today I experienced the same problem. Files that previously opened normally now no longer open showing the behavior described above

Log:

My system: Ubuntu 22.04.4 Apache PHP 8.2 Nextcloud 28.0.5

When the error appeared it was in the versions Nextcloud 28.03 Dicom Viewer 2.1.0

In an attempt to resolve the error I upgraded to: Nextcloud 28.05 Dicom Viewer 2.1.1 and the error persists

Any solution ?

Same here.
Ubuntu 20.04 PHP 8.2 Nextcloud 28.0.5

[DimonW88]

docker Nextcloud 29.0.0 \ Dicom Viewer 2.1.1 the problem persists
