Matlab takes long time to start, also it lags so much and windows task manager shows very high memory usage. How to fix this?

I have installed Matlab 2022 with all toolboxes on my D: hard drive disk, my system C: SSD is almost full ;'( . When I start Matlab, it takes around 5-10 mins to open, then my laptop becomes super slow, matlab doesn't respond most of the time, works really slow, when I check my task manager, I see that Matlab uses aroun 95% of my memory. Is there a way to fix this or just try to reinstall it till it works?

Do you really need all toolboxes? This is a massive overkill.

You can run the installer again and deselect the toolboxes, you do not need. This reduces the amount of space on the drive.

But if the SSD is almost full, a degradation is expected. The professional solution is to cleanup unused files (under Windows: Right click in the explorer on the disk, Clean Up, Cleanup System Files. Then remove old Windows updates, temporary files, old error reports and so on. If this is not enough to get 20% of free disk space, buy a larger SSD and install it.
