Describe the bug
I wanted to use shadowmapping for better shadows, but it's really buggy and gives me Errors only when enabling shadowmapping:

OpenGL-Error: 1282 (Invalid operation)
[Shaders] Error: Invalid program "shadow"

To Reproduce
Steps to reproduce the behavior:

1. Go to the Shadersettings
2. Click on Lightning
3. Activate Shadowmapping

Expected behavior
Shadowmapping should make realistic and good looking shadows..

Screenshots

Desktop:

• GPU: AMD Radeon(TM) (Integrated) Graphics
• CPU: AMD Radeon 5 5500U with Radeon Graphics (Mobile Processor)
• Shader loader: OptiFine 1.19.4_HD_U_I4]
• Shader version [newest]

Hello, could you please specify the appropriate version number you are using instead of using "newest?"

The shader version may be found in the shader settings menu next to the profile button or from the site you've downloaded from. (e.g. Github latest commit, Github 1.3.0 release, CurseForge 1.3.2, Modrinth 1.3.3)

I assume it's from Modrinth or CurseForge?

At default settings, does this issue occur or in other profiles such as HIGH, ULTRA, POTATO?

Please go to your log folder found in your Minecraft folder and delete all files found within the log folder.

Next launch Minecraft and load any singleplayer world with Super Duper Vanilla on in order for the error to be recorded.

After loading Minecraft successfully, you may exit the game and copy the latest.log file in the log folder and paste it here for analysis.
