Hey @bahabryra, here is some basic troubleshooting steps you could try:
1. Uninstall/Reinstall the Zoom Desktop Client. This will update to our latest version of Zoom: support.zoom.us/hc/en-us/articles/201362233
2. Check your WiFi Connection, if unstable reconnect, consider a wired connection, or check out our network troubleshooting articles support.zoom.us/hc/en-us/sections/201740166.
3. Check if your Operating System is able to run Zoom. support.zoom.us/hc/en-us/articles/201362023
After looking into the suggested above, let me know if that helps?
