22.0-Piers_nightly_20260509 and it still freezes. This is on V3 of the FEL TEST.
V4 uses a workaround that allows the test to complete before looping again. However it will immediately stop playing at around ~1:25. Additionally it seems seeking forward (and backwards) causes this file to stop playing immediately.
Here’s a kodi.log using the V3 test file in case it has any ramifications for FEL playback and leads to a solution. I believe this issue was also raised for NG, although many people claimed it didn’t affect their real FEL movie backups. I am just reporting the issue under CE-NO.
