Lightroom Classic does not start.

[eakart]

Version for win10 x64 - does not start and throws a Crash window.

A clean reinstall (removal with registry cleaning) is useless and does not bring benefits. The version is not pirated, but by subscription Photographer.

System: Windows 10, x64, AMD Ryzen 9 3900x, DDR4 - 48gb

At the same time, Adobe lightroom CC (for x32), Adobe Photoshop: 21.2.0 - starts without problems.

What could be the problem?

Many have reported that Lightroom Classic doesn't work on this pre-release build.

I'm afraid there's nothing that you can do about it, as far as I know.
