most likely an incompatible file system. how did you install WLED originally? official web installer or using tasmota or home-assistant?

[PLCHome]

I downloaded all the files here https://github.com/Aircoookie/WLED/releases . Everything works up to 14.4, everything up to 15.0 doesn't work, including beta and rc.

@PLCHome how did you install your first WLED (initially = before OTA update)?

Did you use https://install.wled.me, https://wled-install.github.io/, or a different installation method?

[PLCHome]

I don't remember, it was more than 2 years ago. I think I installed it via webflasher. It's strange that all updates up to 14.4 can be installed. I'm going to get a new ESP.32 and install the firmware via webflasher.

The installation was probably too old. After it worked perfectly with a new ESP.
I did a presets and configuration backup, installed 14.4 via the web flasher. Played everything back. Then an update to 15.0 and it works.
