I am afraid the publisher of PUBG removed the keyboard and mouse support.
They only support controllers now on Stadia.
From a other topic regarding this topic:
On Oct. 6, the Stadia mouse and keyboard matchmaking pool will be closed. Since launch, Stadia has given us the ability to reach a wider audience for new and returning players on an additional platform. As the service evolved, we found that a predominant amount of our players preferred to play with a controller. Due to this, we’ve decided to focus on the Stadia controller matchmaking pool, helping maximize our Battle Royale experience for players and giving them the best experience possible. While the consolidation of both matchmaking pools was explored, we felt that keeping a controller only queue was critical to upholding the competitive integrity of the player experience, as is the case with all our platforms.
