I am using the time doctor 2 application for a long time. I am using it to track my and my team's working time. Because they are working for me remotely.
2 days ago I update my ubuntu from 20 to 22, then that application stop working. The view is completely blank of that application. I contacted them and did not find any proper instruction to solve the issue. If anybody has already solved this issue by finding any dependency installation on Ubuntu 22 then it will be a great help for me.
I faced the same problem a week ago. Also contacted the support team and they took a remote session but could not troubleshoot this issue. Then they suggested downgrading my OS. I reinstalled Ubuntu 21.10 and now it is working perfectly again. They also said that they will pass this message to the product team. Let's see when they will update the application which will run on Ubuntu 22.04.
So, I think that there is no other way except to downgrade the OS.
The support team didn't have a solution for me. However, I found a workaround that helped here.
Run the following command in terminal
export QTWEBENGINE_DISABLE_SANDBOX=1
Then run:
~/timedoctor2/timedoctor2
Note: I needed to run again after closing the terminal.
