After Effects crashes constantly, black screen and windows become unresponsive

After Effects crashes constantly, black screen and windows become unresponsive.

This happens about last week. Everytime I scrub any file (jpg/png/mp4/vector) After effects lags down, black screen and unresponsive.

Other software I use does not experience this lag. I have updated the Graphic driver, no effects. I’ve changed the settings in AE, so far no effects.

My specs:

• Intel(R) Core(TM) Ultra 7 155H (1.40 GHz)
• 32.0 GB (31.4 GB usable)
• NVIDIA GeForce RTX 4050 Laptop GPU (6 GB)
• Intel(R) Arc(TM) Graphics (128 MB)
• Storage: 668 GB of 954 GB used

Please suggest me what to do about this constant problem. I can’t use AE at all.
