Ihave Version 16.89. How do you downgrade to 16.84?, I am not able to find a way.
All MAC after 2021 change processor from Intel to ARM. M1, M2, M3 .... etc. I think the issue is compatibility with these processors. I dont know if people using Word i a Mac with Intel still faces same problem. There has been compatibility issues in many other softwares usually. ARM usually emulates an Intel processor and work that way, however new packages were developed specifically for ARM processors and the performance is way better than for Windows. I was facing lag issues very similar in the past with Matlab once I started using my M1 Max until they developed ARM specific software which has been working amazingly good. Some software provides the option to chose between Intel or Arm for installing software for Mac.
Which computer do you have?
Thanks I will try to install that version
This is my activity monitor CPU, sometimes says not responding or it is with %CPU 100 or more.

I was successfully able to downgrade to 16.84, however it is still very slow to use. It does not get stuck like the 16.89. However the performance is very bad anyways.
