You did well removing that directory. A website article has some information on clearing codecs and cache like that iirc.
I was offline due to power cuts in California.
As you’re on a Docker, the best I can do is help you to log this with steps to reproduce your issue. If we develop a good basis of evidence, we can ask another Linux pro to help us. You will probably want to explain exactly how you set up your Docker permissions with screenshots etc. Have a read over the Linux Tips here on the forums and let us know what you’ve tried and what you saw.
