Can't Click Anything After Match

Played first Casual Match, looked through battlepass then requed. Got into lobby fine but then couldn't click anything (options, sponsor select, game chat etc nothing). Tabbed out to check mouse working, it works fine on anything other than game. unplugged and re-connected mouse. Used enter key to use game chat and say I was trying to select sponsor but couldn't, one other person on team also had same problem. Match was cancelled due to not picking sponsor and penalty administers. Couldn't click anything in game menus either, even when using Esc button to access menu. Had to force-quit game via Steam as couldn't click to confirm "exit game?" prompt window. Sad though as I was having a lot of fun!!!
