Win7 x64 Ultimate. All previous builds up to (and including) v0.0.32 (Update 11.7, uploaded 2023.02.11) used to work just fine (and still work). The problem appeared since v0.0.33 (Update 12, uploaded 2023.02.18) Update 12, Update 12.1, reuploaded archive with Update 12.1 that was uploaded later and Update 12.2 all show this error message and refuse to launch.
My Chrome version is 109.0.5414.120 (further updates only available for Windows 10 or higher)
Although I can't run specifically the downloadable Win64 version. Web-version in Chrome is working, but overall performance in the browser is beyond playable even with the new low quality option so I need a working downloadable version for proper testing.
I've just asked people in a few Fallout chats to try the current build and at least one Windows 10 user reports no issues (downloadable version runs fine for them) so It's i probably the OS version issue.
