qBittorrent official forums

I'm not sure where to post this.

Just in the past week or so, the program is completely unusable now.

I try to open it and just sits there. (Not Responding)

I actually forgot I started it last night. Left it running all night. Forgot to check this morning as well. So it had been sitting at (Not Responding) for about 22 hours or so.

I'm not sure where to go for help.

Very few users read forums, more active discussions in reddit and unfortunately most contributors, developers and more knowledgeable users read GitHub a lot more often than anywhere else.

When you try to create issue report then before submitting it, you have many important links that explain where to find what, when to use discussions page and how to create a good issue report.

Since you already opened issue report in GitHub then better to continue discussing things there:
