Why are Twitch Minecraft Modpacks opened in the wrong profile?

I have a quick question here. I registered in the Twitchlauncher earlier and wanted to download a modpack for Minecraft. It worked, but when I go to "play", the launcher opens with the Profile Player and it can't be played because this profile was not purchased. But I have a purchased profile. I want the modpacks to be loaded on my purchased profile. It worked a month ago. Does anyone have a solution?

Not really helpful for you now, but I also had problems with the Twitch launcher.

In the end, the only solution was to switch to the technology launcher. I'm very happy with that too.

By opening the Modpacks in Explorer, you can also change them. → you don't need a forge.
