Have the same problem, reinstalling didn’t work for me but a temporal fix is to change the sample rate of the project. What I do is going to Project>Project Setup>Sample Rate and change it to the next value (if it asks you to change your files in any way, don´t do it) and then change it back to the original rate.
Level meters are back, but they´re gone after you save the project and reopen it, got to do the same every time I open the project; hope someone has a permanent solution.
