Have you tried all the solutions in this thread https://forum.plutonium.pw/topic/6832/common-launcher-issues-solutions ?

@Shisuii Can you convert the error to English? Also what antivirus do you use? Try running the launcher as admin as well.

When exactly does the crash happen? Elaborate? Also try quitting/disabling any overlay apps you might have running in the background such as msi afterburner, rivatuner, etc.

all right thank you very muh, keep up the good work !

@HannesC I tried the guide. Doesn't work. it just loads and nothing afterwards

You get that on specific servers or on all of them? Try joining the server you have lowest ping on, doesn't matter if its empty, try joining it. If you can, it's definitely something related to your internet (high packet loss or such) and if you can't, make sure there aren't any 3rd party firewalls blocking Pluto. Also try joining servers through the main menu (before you get into Online and such).

Install everything in the redist folder (dxsetup.exe inside the directx folder as well) and what antivirus do you use? If its defender, follow this video whereas if it's any other trash AVs like McAffee, Avast, Webroot, etc uninstall them.

@Y21HML i don't think that is being tracked correctly atm.

@Chase oh thank you very much. I did that and I can see huge difference in performance now.

Something else caused your PC to restart, not the torrent/torrent client. Probably a windows update. And no the download won't restart, the progress would stay where it was, and would automatically resume if you open qbit again.

@mrbryceguy You could try disabling fullscreen optimizations for the bootstrapper, it's located in C:\Users\YOURUSERNAME\AppData\Local\Plutonium\bin right click plutonium-bootstrapper-win32.exe -> properties -> compatibility -> enable "disable fullscreen optimizations".

@xEdits112 nope, what do you mean by "not properly"?
