I kinda don't wanna be that guy but..

A good place to start fixing things when all else simply won't do, would most of the time be a fresh OS installation.
If you have common sense when browsing the interne or installing the programs you use daily, consider "ameliorating" your OS (read more @ ameliorated.io)

If you play games on that system, consider making a 2nd partition for a 2nd OS installation made specifically for gaming, or get an extra drive specifically for that. The less crap installed on a music production machine that ain't totally related, the better in the long run.

Or, if you're lucky...

System restore to a point where things may've worked.

Use something like "Revo Uninstaller" to:
Completely wipe FL Studio 21, and traces of it in the drive and registry.
Remove drivers for your Focusrite card, aswell as any other ASIO driver you've installed

Reboot, sometimes a clear mind needs a reset.

Then, do a fresh installation of FL Studio 21, and just DON'T INSTALL ASIO4ALL because it's utterly useless today. FL Studio ASIO is a better alternative for other DAW's even by a margin, ironically enough.
Install your Focusrite drivers.

Cross fingers I guess.

 

i fixed it uninstalled and deleted all traces of fl studio 21 and installed version 3713 in programfiles flstudio21.1 now it works yayyyyyyyyyyyyy it was a problem with the new fl studio versions

 

I see.. Never had problems with the new updates but good to know it worked with an earlier build.

 

There are lots of complaints about them and people downgrading to earlier builds of FL. Maybe it is getting more complex for them to K it, and they keep adding more features. On top of that, they have some pretty dumb default settings in preferences which do not help at all.

 

I suppose I'm among the fortunate. :P

 

maybe you just know what you are doing.

 

happened to me, so I downgraded to the last crack before this newer one.

 

It`s not related with your hardware or you system, it`s related with this lastest cracked version, so downgrade for the one before that.

Idk if it`s image-line fault or cracker`s fault, but you wont be losing anything, the older version has everything this newer one has too

 

I also have the same problem with Fl Studio 21.1 whenever I try to change my audio driver on audio settings, the program just closes. Kindly Help.. Any tips

 

Here....

to here...

 

Take screenshots of your settings and perform a clean install (clean registry, tick settings when uninstall, tick clean when reinstall) it fixed the issue for me. Set everything up after reinstalling 21.1.0 then uninstall then reinstall 21.1.1

 

Hey, if u fl studio is pirate, unistall the latest versión u installed and install a before versión like 21.0.3, this versión working 100% can change the input and output from fl studio ansío to focusrite, apollo twin, and othes devices with out problem, the fl studio versión 21.1.1 bring the problem can't change the device from input/output and fl studio auto close inmediataly
