Voiceover record bugged

A voiceover I recorded directly into Premiere Pro seems to have something wrong with it. I recorded 5 voiceovers using Rode Wireless Me microphones, 4 of which were short tests. The 5th was a 36-minute interview. I found the files in Premiere's 'captured audio' folder. The tests had been labelled Audio 1, Audio 1_1, Audio 1_2 and Audio 1_3 but the long interview is listed in that folder as "224552b7-d49b-4285-8f27-1eb257466087.wav". I didn't change any settings between my recordings. According to Quicktime Player the audio format of the working files is Linear PCM, 32 bit little-endian floating point, 48000 Hz, which should be the same for the broken file, which does not play in Quicktime Player ("this file isn't compatible"), Apple Music or Finder. In Premiere Pro the file imports but appears empty. In the project timeline, the clip was labelled offline when I first found it broken, 10 days after recording. Linking the 224552b7-d49b-4285-8f27-1eb257466087.wav file put danger stripes on the clip, which was still empty. The file only plays in VLC media player, but is missing its last 7 minutes (from 36min21sec to 19min21sec). I'm using Version 25.1 of Premiere on a 2020 MacBook Air with OS Sonoma 14.6.1
