Hey, so my blood sugar sometimes spike two or more hours after eating and it happens with many different meals. Does anybody has the same problem or have you dealt with it?

Welcome to the forums @Vilius
Are you in the UK? As a Type 1, what medication/insulins are you on? ( I will assume that you are using a rapid acting insulin at meal times).
The size and timing of your glucose spike will depend on what type of foods you eat and how much. Bread and pasta are generally absorbed more slowly by the body than say starchy white rice or some cereals for example.
The activity profiles of rapid acting insulins usually peak at around the 2 to 3 hour mark for the very reason you describe.
Your rapid insulin (assuming you use it) should reduce the size of the peak. Maybe you need more insulin or less carbohydrates in your meal?
Be careful about increasing insulin dosage or cutting carbohydrates and consult with your medical team if you have any doubts about how to manage this with giving yourself a hypo.
You can also try injecting a longer time (20 to 30 minutes) before you eat so that the insulin is already working well when you actually eat. Look up "sugar surfing" and or "dynamic glucose management" on google or Youtube for a better explanation than I can give here. You will really need to be able to watch your glucose levels to make the most of this method.
Hope this helps but ask more questions if needed.
Regards

Yes, many of us find that certain foods cause a very delayed rise.
Pizza is notorious for this. It can give a small quick rise at first, nothing for hours, then suddenly a much bigger rise. I think it has to do with the fat slowing the absorption of the carbs, but there's also something specific about pizza, because other meals with similar macros don't do that to me.
I find carbs with high fiber like porridge or lentils do cause me to rise for a long time, but more steadily.
Also, particularly when eating low carb, large amounts of protein on it's own (such as a big steak) can cause a surprising big delayed rise.
This is all a bit individual specific too, so to some extent it just has to be learned through lots of trial and error.
