Premiere Pro is extremely slow

Question

Hi! I don't know if its a bug or not/ problem with the app or problem with my pc. Yesterday premiere pro worked perfectly fine, smooth, no problem with it. Today when i i started to work on my project i noticed it being very very slow. It had moments before where where it would be slow for a few seconds, but thats it, nothing to worry about. But now its different. I can see what im working on (in the preview tab) and then it goes black, the audio still works fine for a few more seconds and then its starting to distort. Also if i press space to stop the clip, it stops after 4-5 seconds. If i close and reopen premiere pro everything is fine for few seconds and then it happens again. I tried to export the project (40 seconds in total and its not complicated, few cuts, few subtitles, usually it took about 3-5 mins to render) and it takes 15-20 mins for it to render.

Is there something i can do ? I haven't made any change in settings.

I dont know if you need it but here are my specs:

Windows 11 Pro
GPU- RTX 4060 TI DUAL 8GB
RAM- 2x 16GB, 3200
SSD- 1TB SSD m2
CPU- AMD Ryzen 7 5700X 3,4GHz

Delete the Media Cache and Media Cache files:

If that doesn't work, try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If NVIDIA graphics, make sure to use a Studio Driver from NVIDIA (NOT the Game Driver), but not the latest version - it has issues with Premiere Pro.

Go here to download:

Choose Clean installation and don't install GeForce Experience.

If that doesn't work, try creating a new project and import the old one into it.
