As described over on Discord....
After installing game update 0.7.2 and reinstalling modpack (#00 initially), I found that after every match had finished, the end screen would freeze-frame like usual for the background, but then nothing else happened - just the background image, no results panes. If I pressed [Esc], I'd hear the back-to-port sound, but the screen would still show the background freeze-frame. I also noticed that during the game, pressing [Esc] would not bring up the menu, although the game bahaved as though the menu was displaying - no ship/camera control until I pressed [Esc] again.
I uninstalled the modpack from the Windows uninstaller, and checked WOWS game integrity. I then played a no-mods game with no issues at all. I then downloaded the modpack again (#01 this time) and reinstalled my usual mods. I am now experiencing the frozen screen again.
Logs zip attached.
Many thanks, you rock!
