Windows 7 Pro 32-bit. Updated to 12.0.0.2877. After the update, I can't even launch MultiCommander.
Crash-IDs: 12-X119HS and 12-B119UE
If you need any additional info, ready to send.

Before that, repeatedly updated and didn't experience any problems with the operation or app launch

(Move topic to Beta section, since v12 is only out as beta..)

According to the crashdump it is when trying to read the language file. I can't see exactly what since the minimum crashdump does not contain any data.
The crash location is very strange and should not even be possible to happen.
Maybe <appfolder>\Languages\MC_LangPack_en.zip got corrupted ? can you open that file with Windows Exporer ?

Yes. I can open MC_LangPack_en.zip and MC_LangPack_ru.zip files with Windows Exporer. I even checked the archives for integrity in Winrar 6.11 and 7-zip 21.07 and 22.00- No errors found. Can I provide any additional information to solve the problem?

You can try to install the Microsoft VC Redist 14.32
https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

It should be built into the exe, but Windows 7 is weird. and might require as a side by side install.

Also are you running Windows 7 or Windows 7 SP1 ?

I'm running Windows 7 SP1.

Already had in my system:
- Microsoft Visual C++ Redist 2008 9.0.30729.6161
- Microsoft Visual C++ Redist 2010 10.0.40219
- Microsoft Visual C++ Redist 2015-2022 14.31.31103

Updated to Microsoft Visual C++ Redist 2015-2022 14.32.31326. Rebooted the computer. But nothing helped. Crash-ID: 12-L120AF

I'm running Windows 7 SP1.

- Microsoft Visual C++ 2008 9.0.30729.6161
- Microsoft Visual C++ 2010 10.0.30319
- Microsoft Visual C++ 2015-2022 14.31.31103

Updated to Microsoft Visual C++ 2015-2022 14.32.31326. Rebooted the computer. But nothing helped. Crash-ID: 12-L120AF

Are you really sure it is SP1 ?
Because the crash is in the new unzip code. The new unzip code uses AVX2 CPU instruction for faster performance (If the CPU supports it).
But AVX2 CPU instruction also require OS support and that was not added until Windows 7 SP1. So that would explain the crash.
Not sure if the AVX2 support is something that can be turned off someplace in the OS.

I have it running on a clean Windows 7 Sp1 on a virtual machine.. I don't have one without Win7. can't install that anymore

Edit
you have not by any chance modified the boot kernal parameters and have run

"bcdedit /set xsavedisable 1"  ?

That would disable the OS support for AVX2.  so doing "bcdedit /set xsavedisable 0" should enable it again..

Yes, I'm sure (see screenshot) https://ibb.co/ftxHxqB

Edit
Tried to run
bcdedit /set xsavedisable 0
But the system reported:
"The boot configuration data cannot be opened.
Access denied."
Despite the fact that I am an Administrator

Edit2
Run cmd as Administator
bcdedit /set xsavedisable 0
Operation completed successfully
But again that not helped. Crash-ID: 12-C120RV

Strange, because the crash is that the AVX2 cpu instructions is not allowed.
