Bug - 5.13 GUI freezes while browsing in SFTP

v 5.13 8172
Just after update to this version the GUI started to freeze while browsing in SFTP-3. While the first session is not reacting I can still right click on the taskbar and reopen a session in the new window. This new session works forever while the first one is not responding. The only method to close the first window is to use the task manager.
It is 100% repeatable but cannot identyfy the exact moment so it is nor replicable. To be frank it always freezes in a random moment in the first 5 minutes of browsing. It happens before transferring any files. In this version GUI also displays (refreshes) the local folder very slowly comparing to the previews version so the bug could be there not in the remote connection. Just a guess.

Windows 10 in Polish version, Polish version of WinSCP.
