I had a problem today when I tried to open Celeste. Got a error log about Extended Variants, so I decided to uninstall it, and Celeste worked, but when I downloaded Extended Variants Mod again from game, Celeste crashed and I got this error log :
#weird bug with extended variants
merry hazel
did this happen after installing dependencies in-game
and if so does it happen every time you launch or was it just a one-off
entirely unrelated why is mobile discord so ass garbage how does this even happen
it becomes readable in horizontal mode but damn

this log happened when I installed dependecies in game (extended variants), but this one happened when I opened the game :

entirely unrelated why is mobile discord so ass garbage how does this even happe...
just wtf 
merry hazel
the first error in the log is the more recent one
it adds new ones to the top
not sure what's actually going on here tho
steel crescent
that's super weird
I disables all my mods
extended variants works
but some helpers auto-enabled
all those who have "OUI" (means yes), and game crashes when I download again Extended variants with these mods enabled
I'm like absolutely clueless
@merry hazel I tried one by one and the problem is linked with Max Helping
I absolutely dunno why
@glossy raptor I can't tell you why, but Extended Variants and Max Helping are actually incompatible with the two most recent versions
glossy raptor
Can you post log.txt? 
steel crescent
this ?
also, the problem is when the game starts. I tried to download Max Helping in game, as independency, and game seems work
but it crashes when Max Helping is already downloaded
glossy raptor
Can you try deleting the Cache folder inside of your Mods folder? The game is going to recreate it on launch
steel crescent
that works @glossy raptor !!
