Several Questions/Problems Regarding JetBrains Rider with Coder

Hello! I setup Coder via Portainer with this compose file https://pastebin.com/dWw8fzGW. I created a docker compose template and then on that I made a new workspace for testing purposes since this is the first time I have used Coder. From there, I wanted to use JetBrains Rider to connect to coder so I used JetBrains Gateway and used the Coder plugin and connected to the workspace and all is good. I obviously now want to make a solution for my app and going into new solutions in Rider brings up the usual page to create a solution but its stuck on updating project templates as it says in the bottom left corner and I have neveer gotten it to ever finish. Because of this im unable to create a new solution rendering Coder useless with Rider. One other thing to add is I want to make a Blaze Web App and it says the template is not supported for the chosen target framework as you can see in the picture along with the text that says the templates are updating. This may be related to the problem of it still updating the templates infinitely but if its not, how would I download the proper framework/new version of .net since I don't know how to do this without access to the server like I do with Windows. I have restarted the workspace many times along with the computer hosting it and im not sure how to fix either of these problems. Any ideas?
