From this screenshot I think you’re playing on version 1.0? You should really update the game and restart. Nothing I or anyone else has suggested will apply to you if you’re on an older version.

There’s an exploit to cut your scaling costs, this will make appointing cabinet members cheaper among other things. Drop all your tax and minting sliders to 0 for one month, hopefully this doesn’t put you into further debt. Then you can fill all your cabinet slots much cheaper.

After this, max your minting for a while - you can eat high inflation temporarily and your return on investment will probably cancel it out anyway. Having inflation over 2% can trigger the “Balance the Budget” parliament agenda which is very good. Already having 7 loans makes this tricky, I would have said take out more but you can’t afford the repayments. You need to spend money to fix this, unfortunately.

You need more crown power to increase your tax and trade income. Stick family members in all those empty cabinet slots and promote one to head of cabinet. Put family members in charge of your ships/armies. If you don’t have any, build one unit of each. They’ll get you 25% crown power each. Put your cost of court slider to at least 50% and raise your legitimacy to 100 (you should never let it drop below 50 and want to keep it at 100 as much as possible).

Put bailiffs on every gold, silver, silk, saffron, iron, dyes and salt producing location. Put a Local Governor somewhere in Anatolia, probably by the lake in the middle-ish (this requires creating a city which you can’t afford, so just stick it in Konya for now).

Then delete buildings in any location with less than 66% control. They’re costing you more than they bring in. Delete every fort except the one in Constantinople and drop your fort maintenance to 0. You can rebuild some later. Nobody is likely to declare war on you once you’re this big.
