@TimeFor what a life saver. That was exactly the issue for me. I moved to a new db and watchdog kept breaking with cache errors.
Error: Call to a member function getCacheTags()
Error: Call to a member function getCacheMaxAge()
In my case the issue was both `stable` and `classy`. I removed them on dev as part of updating to 10. I pushed all changes live but never disabled both the themes on prod before doing so thus I got the error. A simple `drush thun stable` and `drush thun classy` solved the issue for me.
Removing the VBO field from the data export view fixes the issue.
You'll face this problem if you've run `composer update`. Revert to the `composer.lock` before update command and you shall be good.
Never mind; I checked the source code and saw the var being defined. A custom patch was applied removing the `clients` var.
