On editor, when I hit play, the time is slower than normal

Literally, on the start editing screen, the time passes slower than normal, resulting in a very laggy and grainy sound, like it’s on a slow motion, but I don’t have a clue on how I did this and what’s goin on… There’s no effects on the track.

Can someone tell me what I need to do to the time get back to normal?

Hi, and welcome to the forum and community.

So, this is a video clip over one hour long. What are your system specs? HDD or SSD? How much RAM? OS? Kdenlive version? Installed or appimage/standalone?
