Hello and welcome!
From your description it sounds like your timing belt has broke. Try removing the oil cap and have someone turn the engine over you should be able to see the camshaft moving.
If you can not see the camshaft, possible baffle in the way, you will need to remove the upper plastic timing cover and check the belt. With the cover removed turn the engine over the camshaft gear should be turning.
You should be able to remove the upper 10mm bolts and just pull back the cover to look at the belt without fully removing the cover.
