Taskbar error

[quick iris]

The taskbar and everything in general no longer has images and it looks really bad.

Is Linux mint 22.3 Cinnamon

[marble vault]

click on the terminal icon there

does it open?

if so, run inxi -S

capital S

and confirm what it states for desktop

you probably just deleted the start menu

if it's cinnamon desktop for sure, run cinnamon-control-center in terminal

then settings window opens; go to Applets

add the cinnamon menu back

Doing this opens this part here

My file explorer also appears like this.

Resize it big

You could try to reinstall the start menu.
I use LMDE and here it is mintmenu.
"sudo apt search mintmenu" should show you if it is available on LM.

they're also missing the main icons in nemo.

so obviously something they did gave this very bad result.

OK, then it seems the user profile is corrupted.
To be sure, a new user should be create via terminal
"adduser --home /home/tester01 --shell /bin/bash tester01"
login an check if all is fine
If all is fine, restore a backup of the user profile could be very helpful.
