I recently upgraded to 2020b from 2020a. I now get the following error messages upon starting up The first message, I get routinely in 2020a and was hoping that 2020b would fix that error. It seems to arise from the use of the live editor. The other error messages I've not seen before. As matlab.mat could not be loaded, I loaded a copy from another location successfully. I then exited the program from my startup folder and then received the same error message regarding matlab.mat upon starting up the next time. Any ideas on all of these errors???

This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:

For the first series of problems
restoredefaultpath
rehash toolboxcache
savepath
Do you have your own startup.m in your MATLAB directory? If so rename it for the moment.
