In previous versions it was possible to right click on an audio track and instantly view and / or change its gain setting. Now you have to wait a considerable time and if you try to click anything in the pop up window the window freezes or crashes. This is a serious bug that wasn't present in previous versions. Please don't keep adding new features without checking they haven't introduced bugs. An urgent fix is needed.
No problem for me, too

Working fine here in version 12.1 on Windows 10 Pro (1709).
You can also access the Gain directly with the clip selected and the g shortcut.
