I've got some mcpr files created with badlion Client, they are on 1.17.1 which is no longer supported by badlion. So i installed the fabric replay mod, it shows the replays in Minecraft. But when i try to load them, The game gets stuck in The dirt block screen Minecraft shows when it's loading something, without The "loading" text. I took a new replay and it Works fine, but The old ones don't

Badlion uses a modified replay mod, not the official product. Please contact with their support, as you made the replay with it's modified product and we can't predict what they changed.
