My game is able to launch normally, however just before the main screen loads I get the following message:

"Errors during Roughly Enough Items' Initialization"
"Errors: Failed to parse Mod Menu Version: Could not parse version number component 'v1'!"

I've attached a picture of all the mods and clients I use below.
I have 0 experience with coding and developing, so I'm hoping someone will be able to explain as simple as possible what I can do to fix this problem :)
I also apologize if there's a very obvious answer, again I don't have any experience with mod compatibility and coding

I'm using 1.16.5 with fabric loader and optifine using OptiFabric
