Hitfilm Express continuously not responding
I ran Hitfilm express 2022 on Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz, 64GB RAM. The length of video I was working on was around 15 minutes with 640x380 pixels, 30 fps. The problem was Hitfilm express was continuously not responding after a very small editing.
Anyone knows why I got such an issue? I thought the computer should have no problem running Hitfilm express.
Attached picture was from the task manager. I saw 6 C++ Application development framework. I don't understand this.
