Important info: I've been using the Download.bat and Catalog.bat commands (from this guide here: https://itch.io/t/1560831/guide-how-to-use-this-program-for-beginners) to just make it easier for me because I'm a total layman simply trying to download my movies before R18 closes.

My OS version is Windows 10 Home, 22H2, Build 19045.2311

So initially it worked fine, I could download AV from R18 via my Chrome browser, even multiple movies at the same time as well by opening new windows of Download.bat.

But I keep running into the issue pictured below. (Disclaimer: I typed "test" as the content ID but even if I type in an actual ID from a movie I bought I will get the same message, just so you know).

When I follow the filepath mentioned, I tried deleting the folders "ms-playwright", "ms-playwright-go". When I did that and tried using "Download.bat" again after deleting, it will automatically redownload ms-playwright again to that location mentioned in the filepath there in my image. (which looks like this, pictured below again).

As you can see, the download worked fine right after redownloading the Playwright builds. 

But after a bit, it will just give me that message again, and when I check then, playwright.cmd is suddenly gone from the ms-playwright-go folder. I tried copying playwright.cmd to another folder, and pasting it back to that AppData Local path where it belongs whenever I get that error, but that won't fix the issue, instead I now get this (once more see picture below).

Of course, I could delete the ms-playwright folders each time to force a redownload but I will just get the error again after a while. It also robs me of important time before R18 shuts down, since I can't parallel download e.g. 8 AV when I already get this Playwright error after the 2nd or 3rd download. The issue is clearly with ms-playwright, but I don't know why it keeps disappearing from the folder. Any ideas on how to fix this permanently?

I have looked through some other posts and someone recommended downloading and installing MS Visual C++ Redistributable, but it didn't fix the issue for me.

Update: I might have figured out what caused my error earlier.
It occurs when
1.) I open a second "Download.bat" window before the first one has started to display a download progress bar. Essentially when I'm trying to start a second download before the first one even properly commenced.
and
2.) When I open too many downloads at the same time, I think my max was 8 and at the 9th Download.bat window the program just gave up on me and couldn't load the simulation engine any more.
Even though I don't know how to fix it, it's pretty easily avoidable, all in all.

Hi there. Like the error message says, It is likely that you have some AV software which is deleting files or interfering with your install files. For some reason, some AV packages think Microsoft Playwright is a malicious program. The solution is to disable all Windows, and Windows AV software, clean up, and run the program again. It will do a fresh install, and as long as no AV software tries to delete/tamper with it, it should work.
