Is it possible to use previous version of Xamarin Studios?

I updated my xamarin studio today, which was a horrible mistake.
Now I cannot debug no more until app I'm developing crashes.
I am pretty sure this is caused by the update because I cannot recognize any changes in my code before and after update.
This is an error code from my application output:
[] * Assertion at /Users/builder/data/lanes/monodroid-mlion-monodroid-4.8.0-branch/3f1c339b/source/mono/mono/mini/mini.c:3806, condition `l' not met [mono-rt] Stacktrace: [mono-rt] [mono-rt] at <unknown> <0xffffffff> [mono-rt] at *****.OnStart () [0x0005b] in */******/****:391 [mono-rt] at Android.App.Activity.n_OnStart (intptr,intptr) [0x00008] in /Users/builder/data/lanes/monodroid-mlion-monodroid-4.8.0-branch/3f1c339b/source/monodroid/src/Mono.Android/platforms/android-16/src/generated/Android.App.Activity.cs:3488 [mono-rt] at (wrapper dynamic-method) object.bdd34d4d-25c6-43d0-872e-aef57e05c00b (intptr,intptr) <IL 0x00011, 0x0003b> [mono-rt] at (wrapper native-to-managed) object.bdd34d4d-25c6-43d0-872e-aef57e05c00b (intptr,intptr) <IL 0x00022, 0xffffffff> [mono-rt] [mono-rt] ================================================================= [mono-rt] Got a SIGSEGV while executing native code.

I censored part of the text with stars.
And in my code at line 391 there is only if statement
if(1 == bluetoothService.GetState() || 0 == bluetoothService.GetState())
{...}

What is causing this SIGSEV ? Application runs perfectly right when Releasing, but Debug don't work at all.
If you have any idea how to fix this or how to run previous version of xamarin studios I might be pleased.
I also have the same problem! It's really annoying..
Yes ... us too!
Just noticed this post. Looks suspiciously similar to an error I just posted in the Android forum:
http://forums.xamarin.com/discussion/6366/sigsegv-failures-after-xamarin-android-4-8-upgrade
That said, I'm seeing failures in both Debug and Release builds.
Ok. I managed to install Xamarin studio version 4.0.9 instead of 4.0.10. That didn't solve the problem. If anyone wonders how I did it :
-At Xamarin Studios click "Help" -> "Check for Updates"
-Change "Update channel" from "stable" to "beta" or "alpha" (I searched from Beta)
-Found installation files for "Xamarin Studio 4.0.9"
-Hit "Restart and Install Update"-button
That still didn't solve my problem.
I wish ppl at xamarin fixes this bug asap... Untill that, I must keep continue to "debug" with
Console.WriteLine(VariableToDebug);
As i learned from Xamarin, it's possible to download old versions from account page..
serhataydin: Thank you, I'm going to try that out.
EDIT:
Yes you can download older version, but it won't install cause I have Newer version. Oh my... Seems like I need to uninstall Xamarin Studios and then try to install that older version.
I downloaded the older version of Xamarin Android (4.6.8) and installed it, the problem has been gone..
Yo don't need to reinstall Xamarin Studio. Just install 4.6.8, it will downgrade..
It didn't work so well... Still getting the same error while trying to downgrade...
Do you use Mac or Windows?
I use windows. I have tried to uninstall whole program. And reinstall with "mono-android-4.6.08007.msi"
Edit:
.msi file I mentioned earlier keeps saying same error I posted above. XamarinInstaller I recently donwloaded from xamarin sites seems not to install XamarinStudio.
Edit:
XamarinInstaller worked finally. But instead of 4.6.8 Xamarin Studio still seems to be 4.0.10 (build 7).
Ok. I'll give up on trying. I am just wasting my time if I continue on trying. Lets just wait when they manage to produce their next stabile update which may let me continue my work. I try using Visualstudio then.
Hi @MikaKorhonen!
The "Incompatible version of Xamarin.Shell detected" error should be resolved by uninstalling the software through "Add and Remove Programs". However, my guess is that the msi files you are re-installing are somehow still causing the issue. If you could write into [email protected] I can send you the files you need to get everything working again
Thanks!
Hey
I recently took a customer support with xamarin. Have to say that you solved my problems. To solve this I had to remove Xamarin Android and Xamarin IOS from commandpanel->add/remove software.
So thank you Team Xamarin. Now I can continue my work
MikaKorhonen,
Thank you for opening this thread and sharing the solution. I too have problem after upgrading, however, mine is really strange. After I upgrade, all of my apps(without any code changed) will suddenly die after launching. Checking android log says the activity manager facing unexpected fatal error and my main activity has died. I spent a day couldn't fix until I read this post and downgrade back to 4.6.8. Now everything is fine as before.
Thanks again for this thread and look forward to seeing Xamarin releasing any fix.
JesseChang, You're welcome.
This bug is fixed in 4.8.1
Just to report it is fixed in 4.8.1.
I had similar behaviour in SharpSerializer port
