Yes, I tried to use coin control and it writes me that transaction too big (there were 15k bytes).
Correct. There is no way you will be able to consolidate all 90,000 inputs in one transaction. You will need to do it in batches.Quote
If I make a smaller transaction in writes "not in memory pool" in history.
If it is showing as "not in mempool", this is due to your transaction being refused by upstream nodes as invalid. This could be caused by missing inputs, missing signatures, invalid outputs etc... but generally, you should get a popup with an error code+message when sending "fails".Do you get any sort of error message when attempting to send the smaller transactions?
Or does it simply create and entry in "history"?
Is your Bitcoin Core fully synced?

Maybe it makes sense, I put recipient address, which from my Ledger, not generated inside Bitcoin Core.
That shouldn't make any difference... Bitcoin Core is able to send to addresses generated on a Ledger device.
