Does this happen every time when logging in to that server?
Does this only happen on "BotFilter" servers? And not in single player for example?

1. Yes
2. Only servers with "BotFilter". Single player, or any server without "BotFilter" minecraft launch without crash

Only servers with "BotFilter", single player, or any server without "BotFilter"

Hmm what, so "only everywhere"?

If it happens in every world, then what other mods do you have? Something must be breaking the renderer initialization or the schematic world creation.

Only servers with "BotFilter", single player, or any server without "BotFilter"

Oh, I'm wrong, single player or any server without "BotFilter" doesn't crash
May be OptiFabric/OptiFine or Phosphor?

Crash only when BotFilter does falling check, when it successfully check it (only with optifine) and connecting to server (with all mods) game will not crash (BotFilter doesn't check, because it checked me in last 24h)
