The Ottoman stability map and UHV goals are very misaligned

UHV1 = Serbia, Bosnia, Banat, Macedonia, Thrace, Moesia, Constantinople, Arberia, Epirus, Thessaloniki, Thessaly, Morea
UHV2 = Colonea, Antiochia, Charsianon, Cilicia, Armeniakon, Anatolikon, Paphlagonia, Thrakesion, Opsikion, Syria, Lebanon, Jerusalem, Egypt
I chose the yellow despite being hard to see because that is the color the game uses
You have the Ottomans conquering provinces that are destabilizing to possess before they are conquering ones that it is destabilizing to not possess, and due to the timing if you focus on stability buildings you can't get enough units to conquer the provinces or if you focus on units to conquer the provinces you will be collapsing and lose cities due to stability.
Suggested reconfiguration that is also more historically accurate with regard to timeline
UHV1: Constantinople, Anatolikon, Paphlagonia, Thrakesion, Opsikion, Charsianon, Cilicia, Armeniakon, Thrace, Thessaloniki, Macedonia, Moesia,
UHV2: Serbia, Bosnia, Banat, Arberia, Epirus, Thessaly, Morea, Syria, Lebanon, Jerusalem, Egypt, Colonea, Antiochia,
The Ottomans should also have militarism
I have never seen a city in Macedonia by Ottoman start
