Teamviewer and Virtualbox do not start on Ubuntu 20.04

Recently I noticed that the teamviewer and virtualbox do not start on my ubuntu 20.04.
I try to start teamviewer by typing teamviewer on my console Init... CheckCPU: SSE2 support: yes Checking setup... Launching TeamViewer ... Launching TeamViewer GUI . But nothing launched. And for Virtualbox I type $ VBoxManage startvm "win10" --type headless Waiting for VM "win10" to power on... VM "win10" has been successfully started. The vm starts but i don't see the Windows screen although I can ping this win10.
