WordPress Visual Mode Not Working - adding span code while clicking

After the update of WordPress 4.9.6, I got a very strange issue that I am not able to write anything in WordPress editor in visual mode.

When I'm trying to switch from text to visual I am getting this span code instead of text.

span style="display: inline-block; width: 0px; overflow: hidden; line-height: 
0;" data-mce-type="bookmark" class="mce_SELRES_start"/span

Can anyone help me out with this issue? I am not able to write anything.
