We got this error which caused an outage on our website:
An exception occurred: [OTGSToolsetCommonAurynInjectionException] Could not make OTGSToolsetViewsControllersV1Views: Class OTGSToolsetViewsControllersV1Views does not exist in /var/www/vhosts/ourwebsite.com/httpdocs/wp-content/plugins/cred-frontend-editor/vendor/toolset/toolset-common/lib/auryn/lib/Injector.php on line 422
Since it pointed to the Toolset Forms plugin, I disabled it by renaming the folder. The error didn't go however, it showed the same error but a different file, Injector.php somewhere in the types plugin folder. The I disabled Types, then it pointed to Injector.php in the Access plugin. I had to disable all 4 - Views, Forms, Types, Access.
Yeah looks like a missing file, but thought I'd confirm if it's something else. No, haven't updated lately. We're on WP 5.6 with Types 3.4.5 and Views 3.3.5
