Inability to install a specific modpack via CurseForge

[authorless]

The problem is that when loading the ModPack, the Fabulous optimizer (4.0.0-beta.9 for 1.19) an error pops up

{"exception":{"type":"httpException","code":"ERR_NON_2XX_3XX_RESPONSE","url":"https://api.curseforge.com/v1/mods/files","statusCode":400,"body":""},"name":"HTTPException","message":"","стек":"HttpException\n with serializeError (C:\xlauncher\resources\app.asar\dist\index .js:199:69049 )\n on the object.onFailed (C:\xlauncher\resources\app.asar\dist\index.js:201:23175 )\n in C:\xlauncher\resources\app.asar\dist\index .js:152:89931\n in processTicksAndRejections (node:internal/process/task_queues:96:5)"}

To Reproduce

To reproduce, you need to:

1. Open the launcher
2. In the launcher menu, you need to go to the "CurseForge" tab and select "ModPacks"
3. In the search engine, find the modpack "Fabulously Optimized" and try to install 4.0.0-beta.9 for 1.19 (CurseForge) from 14.07.2022 dates

Expected behavior It was expected that the launcher would be able to install this modpack
