Can't see where I'm dragging clips in timeline

It's all in the title, I can move clips (audio, video, adjustment layers...) in the timeline but can't see where I'm placing them in real time. It's been going on for weeks without any improvement. Here are the things I've tried so far :

- Uninstalling / Reinstalling / Installing previous version of Premiere

- Resetting app preferences and clearing cache

- Opening another project to see if it's working there

I'm usually a very nerdy, self fixing things, kind of guy, but I couldn't find any solution on forums, which is why I'm posting here ! It's unbearable, I can't work as fast as I need, please Adobe, help me

Here are my PC specs : 

- Intel i5-12 450H (2.00 GHz)

- RTX 4060

- 16Gb of RAM

- Latest version of Windows 11

- My laptop is a Lenovo LOQ 15, if that can help
