Spoiled textures ETC1, ETC1a

In the previous version 4.18, everything works. In version 4.19 on android etc1 and etc1a loses textures, replacing them with garbage, consisting of color bands and various noises (PowerVR G6200). On (Adreno 306) closes the application after the download screen. PVRTC and ATC work fine. An error was detected after the engine was updated. The test uses Infinity Blade: Effects. As in my project, most textures are not displayed correctly.

If it is unconvincing, I can attach a project or who can tell me that this error is only mine?

Prior to the release of Fortnite developers actively helped in all matters…
