How long after your last mealtime insulin is this?
Are you sure your insulin to carbs ratio is correct, or do you use a different way to decide on mealtime dosing?

What basal (long acting insulin are you on, and at what time do you take it?

Diabetes is complicated and this could be cause by several reasons, including some I have not mentioned. But here are a few possibilities.

For a lot of people, the evening meal is their main meal and more complex than the other meals. That means that it is possible for the blood sugars to continue to rise after the normal two hour period. If you have a cgm, then you will spot this, but if you are just doing a finger prick test after two hours, it is very easy to miss.

When do you take your lantus?
I take mine at night, and sometimes I get the feeling that it has started to run out before the 24 hour period is up. This doesn't happen often enough to be a problem, but apparently it does for some people and their doctor/endo has switched them to use two long-lasting insulin injections, obviously using different type of insulin.

Lack of Exercise in the evening.
Most people work during the day and if your job means you are physically active, then that may have the effect of lowering your daytime blood sugar.
Then after work, you may relax more and take less exercise, which means you aren't using up as much glucose. Hence you may need to increase your 'insulin to carbs' ratio for this meal or take more exercise.

I would also add
- stress during the day causing you to lie awake tossing and turning
- possibly a nightmare. I say “possibly“ because if I wake in the middle of a vivid dream, my BG is always high. I don’t know if the nightmare causes the high or the high causes the nightmare.
- your body may need more basal at night. A twice daily basal may be better than Lantus if that is the case. Lantus can be split but it is not as useful as Levemir.

Can you show us a screenshot of your BG over the evening along with what you've eaten and when, and what you've dosed and when.

I have a rare genetic condition called melas syndrome and the diabetic team said it was a rare type of type 1 diabetes I have,I am also exercise intolerant due to my genetic condition which means I don't burn off as many calories
