Try using the Fabric Loader 0.14.25 Profile in the MC launcher but using the Optifabric 1.13.16 version and Fabric API 0.76.0. Last checked and I could be wrong here but I believe Replay Mod and Optifabric dont work together right now.

Use Fabric Loader 0.14.25. also next time please do a search to see if your issue has already been solved.

I even tried it on 0.14.25, but this time it crashes and gives an error -1. I did everything right, I threw it in folder

You have to use the Launcher to install the 0.14.25 Fabric Launcher Profile. You dont put the Fabric Launcher jar file in any folder. You use the jar file to install the profile I just mentioned.

I put the files in a folder and ran it first on 0.14.25 but it didn’t work. Then I launched Minecraft on 0.15.11, it worked, but this is displayed

If I did something wrong I'm sorry

OK, thank you

Considering I have never bothered or worried about the blur, I wouldn't have any idea.

I did as you said and launched Minecraft and everything worked. It turned out that Optifabric conflicts with with mod Blur I removed this mod and everything works with Replay mod. And can you give me some version of the mod Blur which will work at 0.14.25. And thank you so much for your help and advice. I'm really grateful to you

You're welcome. If this resolves your issue please close the ticket.

Unfortunately, the version of Blur that you have been using is the ONLY version for 1.18-1.18.2. So if that is the mod that is conflicting and causing the issue, then you wont be able to use it.

Are there any replacements for this mod to work with Optifabric?
