What's the problem? Describe what went wrong.

[Certain parts of the game lag consistently. The title screen runs at half speed, then the game runs fine for levels 1 and 2, until level 3 where it begins running at half speed again. Audio is crackled whenever the game lags. The menu that allows you to reset the game or change your controls never lags, however.]

What steps will reproduce the problem?

[Boot up the game in a fresh install of Dolphin and the issue occurs immediately. Play until stage 3 to see the issue mid-gameplay as well.]

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

[Yes, version number 2409-288.]

Is the issue present in the latest release? For future reference, please also write down the version number of the latest release.

[Yes, version number 2409.]

If the issue isn't present in the latest release, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[It is.]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

[CPU: AMD Ryzen 7 5800X 8-Core Processor. GPU: Nvidia GeForce RTX 3060 Ti. Operating System: Windows. RAM: 16 GB. Screen Resolution: 1080p.]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

[None should be necessary, but if anyone would like to request a video of the slowdown happening I can upload one.]
