Additional context
I have tried both java 8,17,and 21 (setting language level to 8) to check if the issue is with jdk but am getting same error for all the java versions

@Ngosti2000 this is failing in the CSS compiler, do you see additional lines above that point that could narrow the problem. If you comment out the CSS does it compile?
Can you comment in/out to find the specific problematic line?

@shai-almog here is the additional stacktrace

i tried commenting the css but still got the error. When i downgraded to 7.0.200, the simulator launched as expected.

This was fixed and merged. If you generate a new project in initializr (once CI completes in 10-15 minutes) it should just work. The CSS part confused me. We use the same CSS process to implement localization and this was a bug with the resource bundle localization logic. Hopefully it's working correctly now.

[Ngosti2000]

@shai-almog, thanks but the issue still persists for my existing projects. I haven't tried generating a new one though as my focus is already existing one.

I'm suddenly seeing what looks like a similar issue in my app with 7.0.236, which is strange because it compiled successfully with 7.0.236 at first.

Since it is blocking compilation, is there a way to work around it (I assume the mentioned fix will only be available in 7.0.237 this Friday)?

[shai-almog]

I assumed this was only impacting new projects not users working on latest. We'll issue a new release sooner.

[ThomasH99]

Thanks for the quick response! Unfortunately, the issue remains on my side (trace below). I'll wait for @Ngosti2000 's feedback and file a separate issue is the fix works for him.

@ThomasH99 It seems that this is caused by a bug in the auto-localization process that produced entries such as this in the resource bundle. You can open the resource bundles in your project and assuming you have entries like:

@im=@im
@im-@im=@im-@im
@rtl=@rtl                                                                                    

Just delete them. You can also delete the common/src/main/l10n directory and the simulator will recreate that.
