First please exclude the TinyMCE editor JS file from Automizer plugin, then delete all cache and reset Autoptimizer cache.
Please navigate to Settings > Autoptimize > Main Tab, click on top right [Show advanced settings] button, find “Exclude scripts from Autoptimize” option, add this JS path ,wp-includes/js/tinymce, than click on [Save Changes and Empty Cache] button bellow.
Second, navigate to Dashboard > Users > Your Profile and make sure the “Disable Visual Editor” is no checked, it should not be disabled.
And third, it seems you have wrong permission in file system. Use some FTP client, make sure the /wp-content/ and /uploads/ and /plugins/ folders permissions are 755 and files are 644.
Don’t forget delete all cache before checking.
After the checking file permissions, please navigate to Dashboard > Forums > Settings > Styles Tab and click on [Update Options] button. This should create a colors.css file in file system /wp-content/plugins/wpforo/wpf-themes/classic/colors.css
Tried everything you said, excluded script, disable visual editor is not checked and all permissions are 755 and files 644. Also went on Styles and clicked update options and deleted all caches. But no luck.
In the meantime I had tried to disable autoptimize, added plugin to disable latest gutenberg builder in latest wp release and tried to genrate colors.css as you suggested but nothing happened.
The forum worked fine until a day or two ago, probably after the latest Wp update it stopped working?

Ok, we found the issue. Probably you have a custom function which adds defer onload='' attributes to the TinyMCE JS file HTML tag and stops it. It should be removed.
<script type='text/javascript' src='.../wp-includes/js/tinymce/tinymce.min.js' defer onload=''></script>
<script type='text/javascript' src='.../wp-includes/js/tinymce/plugins/compat3x/plugin.min.js' defer onload=''></script>
