I am unable to copy any code as I cannot get my application to launch any more: but after installing copilot on posit.cloud there was a memory use of 452Mb or similar, and I was unable to navigate or do anything, with every attempt being met by "Error 405". I am unable to uninstall copilot. I am at a bit of a loss.
So I found a workaround because I needed my data urgently: I upgraded my account so I could allocate more memory. I suppose I will use the upgrade for a month then revert having deleted copilot, as I am only an occasional user. Still, I am feeling slightly sore.
Submitting this for anyone else in a similar situation. There is probably a more sensible way to get it sorted, but I couldn't find it.
