That replay looks broken beyond repair (very similar to this one).
It's the second time I've see a replay like that, in both cases rather long ones.
In the interest of preventing future corrupted replays: What file system are you using? Specifically for the partition that your .minecraft folder resides on, in case you have multiple partitions.
If you don't know, ask your favorite search engine for how to find out.
Here's all that could be recovered from that replay: https://i.johni0702.de/7105.cut.mcpr
The world was missing so I cheated by prepending a different replay in front of the broken one which is why there's a flat world where you spawn.
There are also no other players spawning during the recovered time, which is why the only player in the overview is the one from the prepended replay.
If you know the coordinates of where you stood, you can try going there. To teleport to an arbitrary point, put down a position keyframe, double click it, enter the coordinates, save, the right click it.
All I can see are the blazes spawning, setting in one spot and slowly dying (i.e. suffocating). Not sure what to make of it.
