Why are hot reloads taking so long to do for me?? I make a small change like changing the name of a variable and it takes like 50 to 100 seconds to do the hot reload. When I simply build the solution in Rider it only takes 2 seconds. I don’t know what is causing. Does this info from the output log mean anything?

This is some info from the output log after I cancelled the build. Does any of it mean anything that could be causing the long hot reloads? Let me know.
