have u tried downloading a new teknoparrot from the site to see if a separate install works. i do that from time to time. have u had any other gpus before the 3050 on the same computer? have u tried making sure all the ram is set properly on ur motherboard? if u had other gpus on that computer u can try ddu, which would wipe out any additional drivers / install of the previous setup before upgrading and then see if that fixes the issue. another thing u can do is make a ticket on the teknoparrot github and also post ur troubleshooting log. the ui provides a troubleshooting log that displays the activity. so, it shows what happens between start to finish.
