Weboptions Error Message on Start Up

I get the following error after starting up Matlab2021b. How do I correct the error?

Error using weboptions (line 378)

Arrays have incompatible sizes for this operation.

Error in matlab.internal.doc.updateConnectorDocroot (line 3)

options = weboptions('RequestMethod','post', ...

Hi!, were you able to resolve this? I have a similar problem on R2022a.

[Walter Roberson]

Do you you happen to have SPM installed? Or a package whose name is not coming to mind right now but involves the word 'field'?

Neither of the two, and everytime the message is:

" Error using weboptions

Expected input to be one of these types:

char

Instead its type was string.

Also, the "Sign In" button doesn't work.

Hi,

I had similar error messages coming up on startup of my newly installed version 2022a.

I found this post solved the issue
