I had a similar issue but with an i9/16GB RAM/SSD. Teams would open really slow, hang a lot and the best, drop off meetings in between as soon as I activated other applications. I use Slack/Outlook a lot and this aggravated the problem. Solution was to upgrade to latest Macbook with 32GB RAM. It now runs though I still have issues - just the audio goes out between meetings. I was lucky to have the work laptop upgraded. In short, Teams is crap. My daughter uses Google Meet at school and its so fast/fun/easy on an old 8GB laptop.
