I haven't tried it yet, but wouldn't changing FILEOPEN_READONLY_VERSION to FILEOPEN_READONLY_VERSION_FILTEROPTIONS work?

https://opengrok.libreoffice.org/xref/core/sfx2/source/dialog/filedlghelper.cxx?r=4df292a3cabba02027b993a0805af7018c327182#1506

 // set the read-only flag. When inserting a file, this flag is always set
     if ( mbInsert )
         rpSet->Put( SfxBoolItem( SID_DOC_READONLY, true ) );
-    else if ( ( FILEOPEN_READONLY_VERSION == m_nDialogType ) && xCtrlAccess.is() )
+    else if ( ( FILEOPEN_READONLY_VERSION_FILTEROPTIONS == m_nDialogType ) && xCtrlAccess.is() )
     {

After more than a year, there is no point awaiting for a reply from the author of the commit.

A developer should rather look at all the changes related to tdf 74580.

IDK whether the original reviewer of those patches is still available for LO development, but if there is really an API change (committed more than a year ago ATM) that is causing this bug, it should rather be corrected ASAP, I would guess.

Perhaps the IMPORTANCE of this report should be raised?
