The error is saying that if you are passing any variables / Arguments if those are getting null values then usually this error will appear

So, you check and see
Also, this is using the beta version from studio, recommended to check the error if you are getting from previous process or if you start from new?

Hope this may help you

Thanks,

Thanks for the answer! I installed Studio on another computer and am trying to just log in to it and under my account, but this error appears.

@sozdaiblog

Can you check that is the both system installed with the same community edition and same version?

Thanks,
Srini

Yes, the versions are the same. Yesterday I installed it on one computer, and today on another.

@sozdaiblog

Can you share the screenshot at which screen you are facing this issue with the error appearing?

Thanks,
Srini

It’s mean that you have created a variable but not initialized it. it is a run time error due to initialization.
for e.g, we create a data table variable but do not initialize so it gives us error

Hello! So I’m not creating anything, I’m just trying to open the program

@sozdaiblog

This seems to be error with installation
I suggest to uninstall and re-install

If still you are facing the issue, you better download a stable community version

Hope this may help you

Thanks,

I reinstalled 4 times, it doesn’t help! Can you give a link to the stable version?

I have uninstalled the latest version 2022.10.3 and installed the 2021 version (Luckily I have previously downloaded the .msi file) this resolved the issue for me. after a few days, it got auto-updated to the latest version 2022.10.3 (where I had an issue previously ) and now I don’t see any issue.

It’s in the logs

Open that file and look for dependencies.
Check if dlls for all the dependencies are present.

Hope this is helpful
Cheers
