I have installed TeamViewer on linux mint 20:1. TeamViewer opens in 30 seconds
Same problem. My PC need 35 sec. for booting the Teamviewer service.
I have the same issue, which cannot be necessarily solved by a reinstall. As I did one new nothing changed. Reinstalled TeamViewer and that would not help either. I am on Mint 20.1 now. Unfortunately could not find any evidence in logs or "taks manager" that the app is facing some issue. It just starts as a dormant process and after approx. 20-30 seconds it pops open and it seems to work from there, but is very very annoying. Wish support would do something about it.
