(First time posting on here, im guessing windows 10 mobile means bedrock edition on pc. Also i do not know why there is a MCPE-87833 code)

So it has been about 3 days since i updated to 1.16 and i started to see some crashes, and recently this issue. So basically, at some point i get a lag spike and my fps drops to 1 frame per 10 seconds or slower, and after some lag i get back to 40 fps but there is another problem! My mouse BUTTONS do not register output to the game, i can move around, look around but cannot use right or left click. Yes there has been a similar issue but that issue was told to be a duplicate to another bug that was something very different. Also in that issue, both keyboard and mouse input is canceled, but mouse button input is not. 

The game only accepts movement input from keyboard, so i cannot pause, open my inventory or open chests. Another thing i noticed was, when i move my cursor on the taskbar while the game is open, the game still gets mouse movement input, which is not possible when the game is running normally.

Sorry for not being able to post a video, could not record the game as my laptop is not capable of.

edit: turns out it was an issue on a particular server.
