MetaTrader 5 closes unexpectedly after macOS Tahoe 26.5 update

There are two threads with several posts only (about what to do for example):
MT5 and Mac OS 26.5 compatibility?

Hello everyone,
I am experiencing a serious issue with MetaTrader 5 on macOS. The application crashes and closes completely whenever I execute a manual Buy or Sell market order.
The order window opens normally, but after I click “Buy by Market” or “Sell by Market,” the MT5 terminal immediately closes.
This also happens with all Expert Advisors and indicators removed, so the issue does not appear to be related to an EA.
Has anyone experienced this problem or found a solution?
I can provide the MT5 terminal logs and the macOS crash report if needed.
Thank you.
Thank you for the references.
I will review those threads and collect the requested diagnostic files. The issue described in the Buy/Sell crash thread appears to be identical to mine.
I will post the full MT5 log and macOS crash report after reproducing the problem.
