Severe gameplay lag and freezing in singleplayer and multiplayer leading to instant character death

When playing the game in either Singleplayer or Multiplayer mode, I experience severe gameplay lag and sudden freezes. During regular gameplay or combat, the game heavily stutters or freezes completely on my screen. While the game is frozen, the world keeps running in the background. Once the lag spike ends and the game catches up, I instantly find my character dead without any chance to react.

Note: When playing in multiplayer, my friend does not experience these lags or freezes at all; their game runs perfectly smoothly at the exact same time.

Steps to reproduce:

1. Launch Minecraft Dungeons 2 in Singleplayer or Multiplayer mode.

2. Start any mission and begin exploring or fighting regular mobs.

3. Observe sudden severe lag spikes or complete screen freezing.

4. Wait for the game to unfreeze and observe that the character has instantly died during the freeze.

Observed Results:
The game freezes or lags heavily during normal gameplay, leaving the player vulnerable and resulting in sudden, unavoidable death once the game unfreezes.

Expected Results:
The game should run smoothly without severe lag spikes or freezes, allowing normal gameplay as experienced by my multiplayer teammate.
