This possible error cache in upload file in line 3640 funcction clearcache.

protected function clearcache() {
        $this->cache = $this->dirsCache = array();
                unset($this->sessionCache['rootstat'][md5($this->root)]);
        $this->session->set($this->id, $this->sessionCache);
    }

I decided in my case with isset

protected function clearcache() {
        $this->cache = $this->dirsCache = array();
        if(isset($this->sessionCache['rootstat'][md5($this->root)])){
                unset($this->sessionCache['rootstat'][md5($this->root)]);
        }
               $this->session->set($this->id, $this->sessionCache);
    }

@androidealp When I checked the code, this part was found to be not functioning properly. I will fix this.

Thanks!
