Unlock configuration 2

[koendegroote]

I tried to fix issue with locked configuration in backend due to

bin/magento app:config:dump

But fixes are not working. I followed one of fixes shown in this magento community (from below URL). I have removed all configuration from config.php except modules array list and ran upgrade command. But upgrade command giving me below error and config import stopped in between:

Import failed: Notice: Array to string conversion in /srv/magento/vendor/magento/framework/App/Config/Value.php on line 100

app:config:import failed. See previous output.

Next, I tried with keeping modules and scopes array and this also does not worked. Then I tried with keeping module, scopes and themes array & that's not worked to.

I also know this thread
https://magento.stackexchange.com/questions/208198/configuration-fields-in-backend-are-all-disabled/...

Does anyone know how to get this issue solved?

I'm getting the same error on 2.3.4.

After 6 weeks of research, we started from scratch, now independent of the pipeline roadmap with 2 servers. In January Magento did not yet have a workaround or command to open configuration after: dump although it shouldn't be that complicated to build in such a back door.
