Problems associated with the latest update

I am a Trados Studio 2019 user.
The latest update caused me two problems. First, I cannot access the Find and Replace window. When I click Ctrl+F to bring up the window, nothing appears, except that "Find and Replace" appears on the taskbar. There is nothing I can do. The window is nowhere, and I can only close it from the taskbar by right-clicking it on the taskbar. Regarding the second problem, I don't exactly know when it started and even whether it is related to the latest update. Anyway, I use Google Translation API, but when translating from English into Korean, Google Translation API on the Translation Results window only shows something like "가가가가가가", which means nothing. For the opposite direction (Korean into English), this works fine. Please help me these problems.
