When trying to view any replay, no matter if from a server, or in single player, the game immediately crashes and closes.
I have made one small modification to the modpack (adding vivecraft), otherwise using it as it is available from modrinth.
The latest log of me starting the game, loading a single player world, leaving it, and trying to open the replay of it: https://mclo.gs/tSKQF8R

That looks like it's caused by LambdaMap because it assumes that if you're not in singleplayer, you must be in multiplayer, which is an assumption that's trivially incorrect when considering the ReplayMod.
You should open an issue on their issue tracker if one does not already exist and then, until it's fixed, remove the mod before viewing a replay.

Hey could you help me with my replay? This is my crash report. Thank You

No.

1. Do not hijack random issues, open your own.
2. Update ReplayMod
3. Remove unrelated third-party mods until you have a minimal configuration that exhibits the issue
